Adding linebreaks after sentences in a paragraph

[Aariq]

We talked about how each sentence in a paragraph should be on its own line in a .md doc for ease of tracking diffs, but it's a bit of an unnatural way to write. I wonder if it's possible to use a GitHub action to add these line breaks on PRs? Then folks wouldn't necessarily have to think about doing that. Might be something in here? https://github.com/marketplace/actions/markdown-linting-action Looks like a lot of effort to set up, and as far as I can tell it can only limit line length before a break. Like it can't detect when a sentence ends.
