To offer built-in color output as option

Describe the enhancement
After color output improvements (link and https://github.com/actions/toolkit/pull/583) I think it could be interesting to integrate to this toolkit, as an option disabled by default, color output for the following methods

https://github.com/actions/toolkit/blob/85f6235ca99674b76ff1dbde0683a5e9df71e1d2/packages/core/src/core.ts#L144-L170

Code Snippet

Current

https://github.com/actions/toolkit/blob/85f6235ca99674b76ff1dbde0683a5e9df71e1d2/packages/core/src/command.ts#L32-L34

Change Proposal

import { red, yellow } from 'whatever-lib-to-color-output'

const logColors = {
	error: red,
    warning: yellow
}

...

function issue(name: string, message: string = '', useColoredMessage: boolean = false): void {
	if(!useColoredMessage) issueCommand(name, {}, message)
	else {
		const paintMessage = logColors[name]
		const paintedMessage = paintMessage? paintMessage(message) : message

		issueCommand(name, {}, paintMessage(paintedMessage))
	}
}

Additional information
Here are some comparisons for some packages for coloring the output:

• https://www.npmtrends.com/colorette-vs-kleur-vs-chalk-vs-colors-vs-ansi-colors
• https://npmcompare.com/compare/ansi-colors,chalk,colorette,colors,kleur

In case this feature has sense, I guess it will need to be discussed how and which external package or internal utility to use.

Start with packages/core/src/core.ts lines 144-170 and packages/core/src/command.ts lines 32-34 to map the affected methods and current command output. Review the proposed optional coloring behavior and compare the listed package choices or an internal utility. Done means color output is available as a disabled-by-default option for the specified methods.
