It's a decent idea, but it's weird reviewing code you wrote in saying GitHub, it looks totally different. Imo not a show stopper but a side effect you have to get used to.

I’d like to think that GitHub would be able to display with my editor format settings.

This is disastrously easy to implement with just a few filters on git (clean & smudge).

I highly recommend it though, especially if you worked for a long time at one company and are used to a specific way of writing code. Or if you like tabs instead of spaces...

this works for pure formatting, but falls apart when you start linting to exclude certain syntax or patterns

This is pretty common now. At least my Vim/git combo does this, where I always open source code with my preferred formatting but by the time it's pushed to the server it's changed to match the repo preferences.
