[Prettier Plugin] prettify whitespaces (remove not needed ones)

[keul]

Currently the plugin sorts properly classes, but ignored whitespaces.

While moving/adding removing classes it can happen that some whitespace it left over, like:

className="aspect-[2] w-full max-w-full rounded-3xl"

which is the same as className="aspect-[2] w-full max-w-full rounded-3xl"

I'm wondering if this plugin can take care of also harmonize whitespace usage, by removing not useful ones.
