Tailwind v3 extractor

[frederikhors]

Is your feature request related to a problem? Please describe. Now that Tailwind 3 is really close I think we should update Docs for a custom Tailwind extractor that works.

Describe the solution you'd like With Tailwind 2 we could have used a default extractor that they made available in an internal file, but it was not a public API and in fact it is gone now: https://github.com/tailwindlabs/tailwindcss/discussions/6162.

What to do with Tailwind 3?

Using extractor copied from Tailwind internals changes code from this:

*,
:after,
:before {
	border: 0 solid;
	box-sizing: border-box;
}
:after,
:before {
	--tw-content: "";
}

to this

* {
	border: 0 solid;
	box-sizing: border-box;
}

which is totally wrong (especially for Tailwind 3).

I've also noticed that the default extractor doesn't work for Tailwind's "arbitrary values" syntax.

e.g. if I have text-[10px], it ends up getting stripped.

(For what it's worth, defaultExtractor: (content) => content.match(/[\w-/:[\]]+(?<!:)/g) || [], did the trick for me for the arbitrary values issue.)
