Replaces kolorist with picocolors

[JoviDeCroock]

50kb vs 6kb in package size so that would be a 44kb reduction for us

simple-code-frame relies upon it yet so there's no reduction

Sorry about that, code-frame actually comes from vite-prerender-plugin (which we can probably get away with making an optional peer dep instead?) -- I thought it was a dep here. No reason not to then.

FYI: I wrote the kolorist package. There is nothing in the kolorist package that would be that big. Main difference to picocolors is that kolorist supports ansi256 + true color codes. It's not that much code and we don't use that here so all good with replacing it. We only have two simple color usages in this PR which is nothing 👍

FWIW I knew that at least, but Jovi is referring to the size on disk which is in fact ≈50kb: https://packagephobia.com/result?p=kolorist

Hardly a problem, though I guess it could result in a slightly smaller install (only if we fiddle with vite-prerender-plugin which also uses it of course) 🤷

Ah sorry my bad. Looks like it contains cjs + old style module copies.
