Clarified that the default template uses type hints.

Fixes #8151. The default template did not match what Godot produces with default settings. This change clarifies that this default template includes type hints.

This isn't correct, the template is what the actual template is, it doesn't say that it is the output of the template, but is the template

The type hints are in the template, and removed if not added, see here

It should instead clarify how the type hint system works for templates

It looks like the original issue was that I didn't read the final section on the page that describes how type hints will be removed if the Add Type Hints editor settings is turned off.
