ci: speed up workflow reruns, remove run_number from build cache key (#14448)

Use `${{ github.sha }}` instead of `${{ github.sha }}-${{
github.run_number }}` for the build cache key, which will speed up
re-runs of failed workflows.

This should avoid having to rebuild at all on a re-run, saving ~5mins.
