⚠️ Rebase not applied

This branch has not been rebased, as its update has not yet met the internal checks configured for it, such as minimumReleaseAge. Rebasing it now would add a dependency version which is still within its configured observation period.

Renovate will rebase this branch once its update has met those checks.
