Update the task deprecation template

[EndymionJkb]

Description

The base scripts have evolved since the templates were introduced, and the deprecation seems a bit out-of-date. It's usually unnecessary to modify anything in the input/index files now, and we are skipping the fork test for deprecated tasks.

We've also added the address generator, which is easy to forget about.
