Feature: #34922 - Allow .ts file extension for static TypoScript templates

See forge#34922

Description

Only these TypoScript file names were allowed:

  • constants.txt

  • setup.txt

  • include_static_files.txt

The ts file extension has been allowed for constants and setup and is prioritised over txt.

Impact

There is a little performance impact when loading the TypoScript from scratch like in the backend and frontend without cache as the new file extension is always tested.
