Use semantic markup (modules r-s) (#6683) 
* Use semantic markup.

* Use 'ignore:' for alias reference.

* Ignore sanity errors for older ansible-core versions.

* Improve markup for RHSM modules.

Co-authored-by: Pino Toscano <ptoscano@redhat.com>

* 'ignore:' is no longer needed.

* E() now works better.
