Consider switching from chalk to picocolors

[benmccann]

Is your feature request related to a problem? Please describe.
Work is ongoing to minimize Vite size. Assuming vitejs/vite#6277 is merged, then Vite will be standardized on picocolors

Describe the solution you'd like
It would probably make sense for us to standardize on picocolors to match Vite

Describe alternatives you've considered
If there is a reason to continue using chalk we may want to chime in on the Vite PR. However, I'm not aware of any such reasons

Additional context
svelte-check currently uses chalk:

language-tools/packages/svelte-check/package.json

Line 22 in c978ee1

"chalk": "^4.0.0",

I don't think there's any reason to using chalk specifically, so I'm fine with switching the dependency.
