Use chalk instead of colors for console printing

Colors modifies the string prototype, which is dangerous. Chalk does not.

We do not want to add any dependencies to the typescript pacakge

@mhegazy By "instead" I mean "remove the colors dependency and replace it with chalk." Do you mean you don't want to add any new dependencies or just don't want the dependency graph to get bigger?

[mhegazy]

We do not use colors for --pretty, it is a dev dependency for our test runner. so not sure if that is what you meant or you meant to use color/chalk in --pretty.. i might have miss understood.

[JoshuaKGoldberg]

I did mean the dev dependency, yes (sorry for not being clear).

Much as I love to see america in my completion list for strings, this seems reasonable. As long as it doesn't change things drastically, I think we'd take a PR on this.

[tumulr]

Can I take this one?

[JoshuaKGoldberg]

There's a PR out already :(
