Consider all emojis when deciding what emoji to use for a config

[bmish]

We currently have a list of default emojis for common config names:

eslint-doc-generator/lib/emojis.ts

Lines 5 to 28 in 5446459

	const EMOJI_A11Y = '♿';
	const EMOJI_ERROR = '❗';
	const EMOJI_STYLE = '🎨';
	const EMOJI_TYPESCRIPT = '⌨️';
	const EMOJI_WARNING = '🚸';
	/** Default emojis for common configs. */
	export const EMOJI_CONFIGS = {
	a11y: EMOJI_A11Y,
	accessibility: EMOJI_A11Y,
	all: '🌐',
	error: EMOJI_ERROR,
	errors: EMOJI_ERROR,
	recommended: '✅',
	strict: '🔒',
	style: EMOJI_STYLE,
	stylistic: EMOJI_STYLE,
	ts: EMOJI_TYPESCRIPT,
	type: EMOJI_TYPESCRIPT,
	typed: EMOJI_TYPESCRIPT,
	types: EMOJI_TYPESCRIPT,
	typescript: EMOJI_TYPESCRIPT,
	warning: EMOJI_WARNING,
	warnings: EMOJI_WARNING,
	};

If none of those curated emojis match the config name, we could fallback to checking for any other match in a complete dictionary of emojis based on the standard keywords associated with each emoji.

Potential libraries to help with finding the best emoji for a given config name:

• https://www.npmjs.com/package/node-emoji
• https://github.com/IonicaBizau/emoji-from-word
• This could even be a place to incorporate an AI-powered suggestion

Note that the user can always use to the --config-emoji option to change or remove the auto-assigned emoji.

Separately, we could also add some more default emojis, for things like common frontend frameworks.
