docs: remove Microsoft Teams (msteamsbridge) integration docs

[DeepDiver1975]

owncloud/msteamsbridge is being archived and is no longer maintained (heads-up: owncloud/docs#5125). This removes its documentation from the server docs.

Changes

• Delete the two MS-Teams integration pages:
  • modules/classic_ui/pages/integration/ms-teams.adoc (end-user)
  • modules/admin_manual/pages/configuration/integration/ms-teams.adoc (admin)
• Delete the now-empty classic_ui Integration section (integration/index.adoc, which only listed the Teams page) and remove the Integration block from classic_ui nav.
• admin_manual: drop the Teams entry from the Integration index and nav — the Splunk integration remains, so the section stays.
• Remove the == App: Microsoft Teams Bridge config sample from config_apps_sample_php_parameters.adoc.
• Reword the .htaccess note in manual_upgrade.adoc that xref'd the removed Teams page (kept the WebDav example).

Verification

• grep for msteamsbridge|msteamsgen|ms-teams|microsoft teams across all .adoc files → 0 matches after the change.
• No remaining xref points at any deleted page (the surviving configuration/integration/index.adoc xref targets the admin index, which is retained for Splunk).

Note: the heads-up issue was filed against owncloud/docs, but that repo is only the Antora aggregator — the actual content lives here in owncloud/docs-server.

Also resolves owncloud/docs#5126 (msteamsgen heads-up): the MS-Teams generator and Bridge App are two halves of the same integration and share these same pages, so this removal covers both. Verified grep includes msteamsgen → 0 matches.

• Please remove the relevant data of config_apps_sample_php_parameters in core. I will check that this is then properly removed here in this PR after the core PR is merged. Otherwise any config-to-docs run will re-add the content...

• There are images that need to be removed too. I will take care.

• I also will take care to remove it from the app list

Approve (review-only — self-authored). Clean removal; Antora build safe.

Dangling-xref check (grepped the full PR-head tree 455ae39):

• Zero remaining xref:/link:/image: references to either deleted ms-teams.adoc, or to the deleted classic_ui/integration/index.adoc, or to msteamsbridge/msteamsgen/"Microsoft Teams".
• admin_manual/partials/nav.adoc: only the ms-teams child dropped; integration/index + splunk retained — correct.
• classic_ui/partials/nav.adoc: whole integration section removed (index+ms-teams) — correct, MS Teams was its only content.
• manual_upgrade.adoc:60 and config_apps_sample_php_parameters.adoc (msteamsbridge section): edits are MS-Teams-scoped, surrounding content intact — coherent.

Non-blocking: orphaned image assets remain and are now unreferenced — admin_manual/images/configuration/integration/ms-teams/ (10 files) and classic_ui/images/integration/ms-teams/ (2). Doesn't break the build; delete in a follow-up (or here) to avoid dead assets.

CI green (Build documentation, lint).

Good catch on the config sample — you're right that config_apps_sample_php_parameters.adoc is generated (everything below // header end do not delete or edit this line), so a config-to-docs run would re-add the Teams Bridge block from core.

I've opened the root-cause fix in core: owncloud/core#41668 — it removes the msteamsbridge block from config/config.apps.sample.php (plus a changelog entry).

Once that merges and a config-to-docs sync runs, the generated .adoc here will drop the block cleanly. Happy to revert the manual edit to the generated file in this PR if you'd prefer to let the sync handle it — let me know which you'd like.

The images and app-list removal are yours as noted. 🙏

Took a couple of these off your plate since we were already in here:

• ✅ Images removed — pushed a commit deleting the 12 orphaned MS-Teams image assets (10 under admin_manual/images/configuration/integration/ms-teams/, 2 under classic_ui/images/integration/ms-teams/). All were fully de-referenced once the pages were deleted; grep for ms-teams/ in .adoc → 0 matches.
• ✅ Config sample — root cause is in core, handled separately in chore: remove msteamsbridge config sample (app archived) core#41668 (removes the msteamsbridge block from config.apps.sample.php so config-to-docs won't re-add it).

Left for you, since it's outside this repo:

• ⬜ App list / marketplace — I couldn't find an in-repo "app list" to edit (no .adoc enumerates it), so this looks like the external marketplace.owncloud.com listing, which needs your access. Flagging rather than guessing — let me know if you actually meant an in-repo file and I'll take it.
