[4][5][6] Incorrect Help Screen for Templates: Customise

[ceford]

Steps to reproduce the issue

Navigate to Templates: Customise (Cassiopeia) and select any php file to edit. Select the Help button in the Toolbar.
The Help screen url is https://help.joomla.org/proxy?keyref=Help44:Templates:_Customise&lang=en

Navigate to Help -> Joomla Help -> Templates: Source - Edit
The Help screen URL is https://help.joomla.org/proxy?keyref=Help44:Templates:_Customise_Source&lang=en

This last Help URL is not used anywhere in Joomla

Expected result

Help screens should use the same url

Actual result

Wrong Help screen URL leads to maintenance of unused screen.

System information (as much as possible)

Applies to J4, 5 and 6

Issue confirmed.

Using 5.2 User get a "404 - RuntimeException".

With 5.2 all help screens will give a 404 as they have not been set up yet

This is a tedious problem with the current Help server. The Help pages are not versioned but the server expects them to be. So someone has to tweak the Help server to make Help52 point to Help5.x. And someone has to go through all of the pages in the Joomla Help page list to add a Category link. Only about a hundred of them are listed there out of the 252 available. Perhaps the result of over-ambitious de# the distant past?
