Glob for candidates

[windymelt]

Is your feature request related to a problem? Please describe.

I'm going to use this action to update copyright information in template file (for XSlate template engine) using custom transform feature.

Of course, not all of template contains copyright year information. Currently I have to specify accurate file path that contains copyright year manually.

Describe the solution you'd like

If this action provides option that ignores regex mismatch, I will be able to use glob to specify target candidates.

Describe alternatives you've considered

Additional context

my transform is like this:

jobs:
  update-license-year:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
        with:
          fetch-depth: 0
      - uses: FantasticFiasco/action-update-license-year@v2
        with:
          token: ${{ secrets.GITHUB_TOKEN }}
          path: templates/**/*.html
          transform: '(?<=<div class="copyright">Copyright &copy; )(?<from>\d{4})?(&ndash;)?(\d{4})?'

some of template contains following line:

<div class="copyright">Copyright &copy; 2005&ndash;2022 <a href="https://example.com/">Foobar Inc</a>. All Rights Reserved.</div>

Hi @windymelt! This sounds like a feature we could implement, but let's have this issue open to see if others might find this useful as well. With enough interest we'll implement it!
