Allows require-description to be turned off for specific rules

[mcongrove]

Adds a new option to require-description, called disableForRules, which allows you to pass an array of rules that require-description will not apply to.

Example usage:

"@eslint-community/eslint-comments/require-description": [
	"error",
	{ disableForRules: ["no-unused-vars"] },
],

This can be especially helpful for overrides which are self-evident amongst users of the codebase.

Requested by #134.

Hate to ping y'all, but I'm not sure if you were notified this PR was here because I can't request a reviewer.
