Fixes dev/core#2769 remove quickform hack - we are no longer calling this rule

[eileenmcnaughton]

It adds to confusion and we generally try to get our packages back to 'stock'

https://lab.civicrm.org/dev/core/-/issues/2769#note_63305

UPDATE - I thought civicrm/civicrm-core#21169 (comment) was merged - needs to be merged first

@seamuslee001 this is a follow up to the changes I did for https://lab.civicrm.org/dev/core/-/issues/2769 - ie we no longer need to hack quickform because we are doing validation within CRM and hacking it has downsides

• confusion - per the gitlab
• makes people think that hacking packages is 'ok' since we did it in place x
• at some level all hacks need to be maintained & re-applied on upgrade - they have an ongoing cost

I don't know what over QF hacks we still have ....
