Deprecated notice on CRM_Core_Form::add

On CiviCRM 5.46.3 I get this while editing a condition 'Compare Old Recurring Contribution Status to New Recurring Contribution Status' for CiviRule 'GC mandate complete'

User deprecated function: Attributes passed to CRM_Core_Form::add() are not an array. Caller: CRM_CivirulesConditions_Form_FieldValueChangeComparison::buildQuickForm in CRM_Core_Error::deprecatedWarning() (line 1060 of /civicrm/CRM/Core/Error.php).

(it's possible this is a core bug, but it's showing while using rules, so this seems a good place to park it for now)

Also get it from adding a send e-mail action in CRM_Emailapi_Form_CivirulesAction_Send::buildQuickForm

Also this:

Deprecated function: implode(): Passing glue string after array is deprecated. Swap the parameters in CRM_CivirulesConditions_ContributionRecur_PaymentProcessor->isConditionValid() (line 65 of /var/www/crm.keepournhspublic.com/sites/all/civicrm_extensions/org.civicoop.civirules/CRM/CivirulesConditions/ContributionRecur/PaymentProcessor.php).

(I'll try to take a look at these but at the mo having trouble forking the repo in lab).
