Description

A new release should not be created if there are no changes since the previous one (ref: https://github.com/projectdiscovery/team-backlogs/issues/228)

I was looking at this other day to update release-tag.yml and found something like below can be used to get commit count from last tagged release, we probably need to use this information in next step to run only when get_commit > 0

    steps:
      - name: Check out code
        uses: actions/checkout@v3
        with:
          fetch-depth: 0

      - name: Get Commit Count
        id: get_commit
        run: git rev-list  `git rev-list --tags --no-walk --max-count=1`..HEAD --count
