Fix the install command for the new Vite frontend

[tonysm]

Looks like the install command doesn't work with the new Vite frontend setup from Laravel. Needs fixing.

I went through the broken setup pretty fast, but from what I could see:

1. Remove the CSS import from our trix-webpack.js (file) - btw, the naming needs to change, I guess
2. Add note about adding the @import "./_trix.css" to the main resources/css/app.css file - maybe Laravel's default scaffolding could change to use @import instead of @tailwind (I'll see if that can be contributed) Edit: prepend the @import './_trix.css'; line to the main CSS file (should work just fine)
3. Find a way to append the new <x-rich-text-trix-styles /> to the templates' head (for both Breeze and Jetstream)

Sent PRs to Breeze and Jetstream to see if we can switch back to using @import instead of @tailwind Edit: no need to switch everything to @import, we can just prepend the line to the main file and the @tailwind and the @import should work just fine.

This was fixed and shipped in https://github.com/tonysm/rich-text-laravel/releases/tag/1.6.0
