An update to the react typings were automerged because the passed the CI.
In reality they broke the frontend build. Addings this job will make
sure that the frontend always builds after updated dependencies.
Some 3rd party nest packages depend on Nest 7 while we use 8. In practice
this still works, but the usual dependency resolution fails and requires
an explicit override.
This should also unblock auto-merging for renovate, as that currently fails
in CI on the `npm ci` step.
