Repo: Rule [options] parameter should be non-nullable if defaultOptions exists

[JoshuaKGoldberg]

Suggestion

Right now, if a rule is created through util.createRule with defaultOptions, the create function's second parameter is an array whose first element is still Options | undefined. That means folks have to !. For example, in #5327:

typescript-eslint/packages/eslint-plugin/src/rules/lines-around-comment.ts

Lines 136 to 137 in 7f2661f

	create(context, [_options]) {
	const options = _options!;

Unless I've grossly misinterpreted the rule options, those ! should be unnecessary, right?

Edit: here's a TypeScript playground with an isolated repro.

We've deleted lines-around-comment in the v8 branch. A new still-in-the-repo example is consistent-type-imports:

typescript-eslint/packages/eslint-plugin/src/rules/consistent-type-imports.ts

Lines 89 to 98 in e408b93

	defaultOptions: [
	{
	prefer: 'type-imports',
	disallowTypeAnnotations: true,
	fixStyle: 'separate-type-imports',
	},
	],
	create(context, [option]) {
	const prefer = option.prefer ?? 'type-imports';

#9025 touches a lot of the same interfaces, so marking as blocked on that one till it's merged.
