Adapt stubPath special-casing to latest changes

[rchl]

In #11480 I've removed redundant workspace/configuration requests but I've missed this special-case logic in vscode extension that removes stubPath property if it's at default value.

Without this change, the server would receive the default typings value and complain that the path is not correct (in logs only, I believe).

The section rename is correct but incomplete — the guard and delete inside the loop still assume the old 'python.analysis' shape. Both need to be updated to operate on the nested analysis.stubPath so the default typings value is actually stripped (and a user's custom stubPath is preserved). A middleware test would prevent this section→shape coupling from regressing.

[rchiodo]

The migration to section python is only half-done. Since the server now reads stubPath nested under analysis, both the user-set guard and the delete need to target analysis.stubPath (guarding against a missing analysis). As written the delete no-ops and the default typings is still forwarded, so the reported log complaint remains.

The section switch to python needs matching updates to the stubPath handling below it: both the user-set guard and the delete still assume the old top-level python.analysis shape, so they now target the wrong key/depth (result[i].stubPath and python.stubPath) instead of result[i].analysis.stubPath / python.analysis.stubPath. As written, the default typings value is still forwarded, so the fix is incomplete.

[rchiodo]

The migration correctly forwards section python and targets the nested analysis.stubPath, matching the server's pythonSection?.analysis.stubPath read. Two small, non-blocking suggestions inline: guard the delete with optional chaining and add a middleware regression test for the strip-vs-preserve contract.
