fix(ci): ignore failing peer resolution

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.
