Add a Merge Tag modifier to the Entry moderation Merge Tags to output the URL only

[rafaehlers]

There's no way at this moment to just output the URL for the entry moderation merge tags.

This will be useful for so many use cases, including generating a QRCode, as requested by a user.

@rafaehlers,the issue wasn't clear about adding a new (:url) merge tag modifier. Your "related" code link pointed to where the merge tag can be modified using a filter, and that's what was done here as well. It would have worked for the customer who asked for this. This is consistent with how we modify other links (e.g., gk/gravityview/widget/search/clear-button/params).

add_filter( 'gk/gravityview/entry/approval-link/params', function ( $params ) {
    $params['format'] = 'text';

    return $params;
} );

If a new merge tag modifier is needed, please update the issue with more details and I'll implement that.
