Changelog link checker

This GitHub action blocks pull requests that include invalid links in changelog files. It is compatible with the changelog format used by the microsoftgraph/microsoft-graph-docs repo.

Setup

1. OPTIONAL: Create a label in your repository named invalid links. The action will flag pull requests with bad line endings with this tag, and will create it if it isn't present.

2. To install this action, create a .yml file in .github\workflows directory, with the following syntax. See Inputs below for info on the inputs. (See test.yml in this repository for an example).

   name: Changelog link check
   
   on:
     pull_request:
       branches: [ main ]
   
   permissions:
     pull-requests: write
   
   jobs:
     check_pull_request:
       name: Check files for broken links
       runs-on: ubuntu-latest
       steps:
       steps:
       - uses: actions/checkout@v4
       - name: Validate files
         id: validate
         with:
           repoToken: ${{ secrets.GITHUB_TOKEN }}
           changeLogDirectory: test-files
         uses: microsoftgraph/changelog-link-check@v1

3. If you wish to block merges that are flagged by this action, set the Check files for broken links check as a required status check.
