Query Title: Changes filters for removing archive title prefixes

[Mamaduka]

What?

Resolves #49001.

PR updates the block filters used for removing archive title prefixes.

Why?

The get_the_archive_title title only works with default priority when the showPrefix setting is true.

How?

The block now uses get_the_archive_title_prefix with __return_empty_string as a callback. When there's no prefix, the get_the_archive_title() method will return just a title.

Testing Instructions

1. Open a Site Editor
2. Create an archive template if there's none.
3. Insert the "Archive Title" block, a "Query Title" block variation.
4. Add the following filters to your codebase:

add_filter( 'get_the_archive_title', function( $title ) {
	return 'Hello ' . $title;
} );

5. Confirm filter is applied no matter the showPrefix setting value.
