Improve detection of files that need to be linted about chktex-action HOT 3 OPEN

Looks like I can maybe get it from the GITHUB_EVENT_PATH env var shown by Jess here

https://blog.jessfraz.com/post/the-life-of-a-github-action/

And seems to be documented in the webhooks here: https://developer.github.com/webhooks/#events

Need to figure out what in the payload content can tell me what files were changed in the PR

from chktex-action.

Looks like https://developer.github.com/v3/pulls/#list-pull-requests-files

And I can

GET /repos/:owner/:repo/pulls/:pull_number/files

Look for the status field and ensure it's not removed (what is the exact string there?), and then deal with pagination. Maybe time to drop to a python API client...

Got the python api and can get the pull request files info using
