Create/use a GitHub Action to remove trailing commas?

[obfuscated-loop]

Hi there,

I noticed that quite a lot of PRs revolve around removing trailing commas from the JSON files. I thought it might make sense to create a workflow that uses a GitHub action to remove these. After a brief search, I wasn't able to find one that exists already - but I still think this would be a good addition and would cut-out a lot of PRs where a single char is removed.

EDIT: We could create a JavaScript action and use an NPM package such as strip-json-trailing-commas

The actions were recently updated to detect errors such as trailing commas, see ScoopInstaller/GithubActions#39
