This PR introduces a script that validates/verifies bug report issues to make sure they have a log file as a GitHub attachment. Any invalid issues will be closed with a comment explaining what they need to do - if they go back and fix the issues, then it'll automatically be re-opened.

This is achieved through a regex and a glorified Javascript... script that runs any time an issue is opened, edited, or reopened. This is a bit hacky (as with almost everything GitHub Actions), so please feel free to point out any adjustments you want to make. This PR can be tested on my fork just by creating an issue, so feel free to use it.

Special note is the closing/opening messages, which may need changing.

(This may or may not require making it so actions can read and edit things, as well as work with PRs - I'm not sure. Just note that I tested with everything enabled.)
