Support for variable and regex usage in repos

[gopinathbg]

1. Can a variable be used for repos?

group:
  repos: |
    ${{ inputs.REPO_NAME }}

if so, could you please provide me an example?

2. Can the repos accept regex patterns so that sync happens for all matching repos?

group:
  repos: |
    org/poc-repo-*

Thanks
Gopi
