🚀 Feature: Replace ansi-colors with a faster, smaller alternative

Feature Request Checklist

• I have read and agree to Mocha's Code of Conduct and Contributing Guidelines
• I have searched for related issues and issues with the faq label, but none matched my issue.
• I want to provide a PR to resolve this

Overview

Coming over from #5274 ansi-colors has a couple issues:

• It was last updated 3 years ago
• Is >2.5x the unpacked package size (26.1 kB) than the two smallest alternatives: ansis (6.8 kB) and picocolors (6.4 kB)

Suggested Solution

I personally propose switching to picocolors. It's the smallest of the popular alternatives that I know of. It's also quite widely used at ~60m+ weekly downloads, showing it should be stable enough for Mocha.

Alternatives

ansis is great too. It's only marginally larger than picocolors, with a small enough difference that they're effectively the same. And at ~1m weekly downloads it's pretty popular in its own right.

Since Mocha uses only single colors, Picocolors is the best choice for this use case. In this case, Ansis has no advantage over Picocolors. However, Ansis is better suited for more complex use cases, when, e.g. using ANSI 256 or Truecolor.

So, I'm for migration to Picocolors, it’s a reasonable decision.

cc @mochajs/committers - WDYT about going with Picolors?

picocolors looks good to me esp as it explicitly supports old node versions :)
