@bkeryan Can you expand on what you expect for 'run again with cached venv'? Would this involve adding a 'use-cache' input to analyze-project to determine if it caches the venv?

Run another job that uses the same venv. Use needs to ensure that it runs after the first job.

Example: https://github.com/ni/python-actions/blob/main/.github/workflows/test_actions.yml#L68

  test_setup_poetry_cache_hit:
    name: Test setup-poetry (cache hit)
    runs-on: ${{ matrix.os }}
    needs: test_setup_poetry

test_setup_poetry_cache_hit also does extra validation that I'm not expecting here. We should probably do that validation when we extract a cache_venv action.
