/**
 * Filter to add Custom Theme, or Plugin templates
 *
 * If you want to add custom templates, this is the hook you should use.
 * Custom templates should follow the pattern below.  Templates should be placed inside the 'templates' array key
 * which is an array of non-key arrays.
 *
 * For the email template post content, you should NOT use HTML as this will be stripped if the user sets the email type
 * to plain text.  Instead, you should use new line breaks (n), which will be converted to HTML <br> automatically.
 *
 * Supported shortcodes (NOT WordPress shortcodes, this plugins shortcodes) can be used in almost every field (to, subject, post_content),
 * except post_title.  If you want to add custom shortcodes, @see WP_Job_Manager_Emails_Shortcodes
 *
 * The `action` value in the template array of arrays should be the action to associate the template with.
 * This is the key of the action/hook, defined in this class, or extending classes @see init_ps_actions() @see init_actions()
 *
 * @see https://plugins.smyl.es/docs-kb/adding-custom-plugin-or-theme-email-templates/
 *
 * @since 2.0.0
 *
 * @param array $templates    Array of templates based on active/available hooks
 * @param array $ps_actions   Array of Post Status actions/hooks
 * @param array $core_actions Array of Core actions/hooks
 * @param class $this         Access to $this current object
