Fix module references in documentation to use FQCN

[geerlingguy]

SUMMARY

See: ansible-collections/overview#45 (comment)

the M() and :seealso: sections in each module's DOCUMENTATION block need to use FQCN.

For modules in a collection: M(community.general.apt_rpm)
For modules in ansible-base: M(ansible.builtin.yum)`

More generally, I think I'll also take a pass at making sure all the README and docs refer to the FQCN version of the module to prevent any confusion, while still adding a note that for transitional playbooks you can use the collections keyword, but to prevent potential issues further down the road, it's a good idea to use the FQCN.
