Filter to set number of fragments

[dgnorrod]

Is your enhancement related to a problem? Please describe.

I would like a convenience filter to set the number of fragments for all or any fields.

Designs

Change includes/classes/Feature/Search/Search.php from:

$formatted_args['highlight']['fields'][ $field ] = [
				'pre_tags'            => [ $opening_tag ],
				'post_tags'           => [ $closing_tag ],
				'type'                => 'plain',
				'number_of_fragments' => 0,
			];

To:

$formatted_args['highlight']['fields'][ $field ] = [
				'pre_tags'            => [ $opening_tag ],
				'post_tags'           => [ $closing_tag ],
				'type'                => 'plain',
				'number_of_fragments' => apply_filters( 'ep_highlight_number_of_fragments', 0, $field ),
			];

Describe alternatives you've considered

I have also considered modifying the formatted args, but this seems easier.
