Breaking: #63110 - alt_doc_nodoc.php removed

See Issue #63110

Description

Script entry point typo3/alt_doc_nodoc.php and NoDocumentsOpenController class are removed without substitution.

Impact

A script pointing to this file resource will trigger a 404 server response and a script instantiating the class will cause a fatal error.

Affected installations

An extension needs to be adapted in the unlikely case that it uses this code.

Migration

Redirecting to typo3/dummy.php instead.
