build: skip waiting for formality check on bot PRs

Automated translation updates from Weblate and dependency bumps from
Dependabot do not trigger the formality webhook [1].

Consequently, the build workflow hangs indefinitely
on the 'Wait for FormalityCheck' step and
subsequently fails/times out.

- Let's skip it entirely for weblate PRs and do not build packages with
new translations as we discussed it and we don't need it currently

- Allow building packages for other bots as Dependabot, Copilot,
because sometimes they can introduce breaking changes and we
need to know, if it does not break CI/CD stuff.
