ci: remove commented profile checks from build jobs

There already exists a workflow dedicated to profile checks:

* .github/workflows/profile-checks.yml.

Keep the build and lint jobs separate to make it easier to spot build vs
lint failures in CI.

See also commit c3b42dbd2 ("ci: disable sort.py on gitlab jobs as well",
2023-04-10).
