Docs: Add button to report python API documentation issue

Adds a button similar to the user manual at the bottom of each page.
This is done to give people a place to report issues other than the documentation repository which should be limited to the user manual.

With this change also comes a new issue template with helpful text and a redirect for people looking to submit an issue with Blender.

I would also like to add a Documentation label too but that requires configuring with the Gitea project.
