Fix broken filterTable testing helper

[austincarpenter]

Currently it's not possible to use the filterTable() testing helper in the way described in the docs for anything other than a basic Filter filter)

filament/packages/tables/docs/06-testing.md

Lines 114 to 130 in c104493

	If you'd like to set the value of a `SelectFilter` or `TernaryFilter`, pass the value as a second argument:
	```php
	use function Pest\Livewire\livewire;
	it('can filter posts by `author_id`', function () {
	$posts = Post::factory()->count(10)->create();
	$authorId = $posts->first()->author_id;
	livewire(PostResource\Pages\ListPosts::class)
	->assertCanSeeTableRecords($posts)
	->filterTable('author_id', $authorId)
	->assertCanSeeTableRecords($posts->where('author_id', $authorId))
	->assertCanNotSeeTableRecords($posts->where('author_id', '!=', $authorId));
	});
	```

This is due to a few incorrect parameter/return types referencing Filter instead of BaseFilter. This PR fixes those.

May also be worth it to document the usage of testing a MultiSelectFilter with an example by passing in an array, although I'll leave this one for the reviewer to decide and implement how they wish.
