Try to avoid module-related tickets in the core Ansible project (#17047)

* Try to avoid module-related tickets in the core Ansible project

Since most users still report module-related problems in the Ansible core GitHub project, I added a warning at the top of the template.

Maybe it could help if the various projects would have more specific names ?

 - ansible/ansible  ->  ansible/main (or something even better ?)
 - ansible/ansible-modules-core  ->  ansible/modules-core
 - ansible/ansible-modules-extras  ->  ansible/modules-extras

I am sure someone can come up with perfect names ;-)

* Remove 'module' from the component options

I would prefer to again note that modules should go elsewhere, but don't want to bloat the text too much.
