Support for Wayfinder hover links to controllers

[N1ebieski]

This PR adds “Go to controller” hover links for all Wayfinder definitions.

The feature uses VS Code’s built-in AST for TypeScript files, so it works in .ts and .tsx files, but not in .vue files. Supporting .vue files would require a separate parser, which feels like overkill.

It needs more testing (I rarely work on large React projects) and probably some performance optimization.

This PR probably makes no sense, because the @see docblock can look like this:

/**
 * @see [\App\Http\Controllers\Settings\ProfileController::edit](/var/www/react-starter-kit/app/Http/Controllers/Settings/ProfileController.php)
 */
export type Response = Inertia.Pages.Settings.Profile;

and VSCode automatically links to the file. The only issue is that it doesn’t link to a specific line number.

It's a shame I didn't know this earlier :/
