Description

Some changes that were in #787 and missed in the version in master.

At the moment on CI prettier is run with --write, meaning I think any error would not cause an issue because the files would also be 'fixed' on CI.

With this PR we now enforce that prettier has been run on the files as they are in git, and also on every file type that prettier understands.

It also adds a few more extensions to the precommit hook, and removes the --plugin flag because it shouldn't be needed given the plugin is listed in the config file :)

Your PR title doesn't match the required format. The title should be in the conventional commit (https://www.conventionalcommits.org/en/v1.0.0-beta.4/) format. e.g.

Thanks for opening this one! Very sorry I missed that. As soon as CI is done we'll merge.

OK so we're getting a weird one:

> @rollup/plugins@ prettier:check /Users/powella/code/rollup/plugins
> prettier --check .

Checking formatting...
[warn] packages/dynamic-import-vars/CHANGELOG.md
[warn] Code style issues found in the above file(s). Forgot to run Prettier?

I can reproduce this locally. However, when I run pnpm lint:docs the file doesn't change. When I run npx prettier --write packages/dynamic-import-vars/CHANGELOG.md, the file changes. Super weird.

Diff looks like this:

diff --git a/packages/dynamic-import-vars/CHANGELOG.md b/packages/dynamic-import-vars/CHANGELOG.md
index f8e17bf..219d285 100644

Got it. CHANGELOG files weren't in the glob.
