Rework TSconfig mod.web_list.newPageWiz.overrideWithExtension
In #70055 the newContent/PageWiz was reworked and mod.web_list.newContentWiz.overrideWithExtension was replaced by mod.newContentElementWizard.override. But for mod.web_list.newPageWiz.overrideWithExtension it was forgotten and so this part isn't useable now, as PagePositionMap links to pathToExt/mod1/index.php (which also misses CSRF protection).
[!!!][BUGFIX] Allow override of page creation wizard again
The TSconfig option to override the page creation wizard via
`mod.web_list.newPageWiz.overrideWithExtension` is impossible
to use anymore since TYPO3 v8, due to the limitation
of the entry-scripts which are only allowed to be in typo3/index.php
for the backend. The option `mod.newPageWizard.override` was
introduced to register a custom route / module to be linked when
adding new pages.
