Term select field improvements

[Gnodesign]

Changes Proposed in this Pull Request

This enhancement will enhance and broaden the current functionality of the term-select-field.php. Presently, the term-select field operates in a manner where it does not allow for the display of a default placeholder; instead, it defaults to displaying '-'. Unfortunately, there is currently no method to alter this default behavior.

With the changes added to the template, the select field will show the field's placeholder as a default option.

Testing Instructions

• Add a new taxonomy
• Add the field to the submission form

frontend_wpjm_fields( $fields ) {
	$fields['job']['job_listing_qualification'] = [
		'label'       => esc_html__( 'Job Qualification', 'cariera' ),
		'type'        => 'term-multiselect',
		'taxonomy'    => 'job_listing_qualification',
		'required'    => false,
		'placeholder' => esc_html__( 'Choose a job qualification', 'cariera' ),
		'priority'    => 7,
	];

        return $fields;
}
add_filter( 'submit_job_form_fields', 'frontend_wpjm_extra_fields' );

• Check the field in the job submission form
