Let's wait to merge this until we get #178 in

@askvortsov1 What's preventing that being merged at the moment, out of curiousity?

I keep forgetting to leave a review 🙈

I don't like how the PHP codeblocks are being formatted...
It also sets the PHP code indentation to 2 spaces instead of the current 4 we have.

[askvortsov1]

Agreed, can we keep the 4 spaces?

@davwheat After #374 and #334 are merged (or closed), could we rebase this and adjust for Docusaurus? We'll also only want to apply prettier to the English docs, since translations will be managed via crowdin.

We're already on Docusaurus (docs.flarum.org), which is why there were a bunch of merge conflicts in that PR. It should make translations easier to maintain (crowdin provides a GUI, plus you dont need sidebars for each language, and the file organization is a lot neater, and a few other things).
