Identify repos for some itegration testing

[nschonni]

EX: Markdownlint lint identifies a few large sample repos to do some integration testing so changes can get a little smoke testing https://github.com/DavidAnson/markdownlint/blob/main/.github/workflows/test-repos.yml
https://github.com/DavidAnson/markdownlint/blob/b8e8609f5fc12abdb7ae6fa6ee1012ce20d3d9dd/package.json#L23-L32

Not sure which ones would be considered good candidates for this repo since there are a lot of dependants on https://github.com/github/eslint-plugin-github/network/dependents
