Maintainer changes

This version was pushed to npm by GitHub Actions, a new releaser for vitest since your current version.

[ogazboiz]

closing this one. it was opened by the per-directory dependabot npm entry (/frontend or /backend), which only bumps that directory's package.json without updating the workspace root package-lock.json that ci runs npm ci against, so it fails install with "lock file's X does not satisfy Y". i fixed the dependabot config in #772 (root workspace entry only). once that merges, dependabot will re-propose the relevant bump from the root entry and it will install cleanly. not a problem with the bump itself.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
