[DerJanniku]

Reviewed. Dependency bump looks reasonable, but this touches backend runtime and our current CI does not build/test the Rust backend yet. Recommendation: merge only after adding a backend CI job or after a successful manual backend build in this branch.

[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.
