fix: cannot use community-general version 12 - no py27 and py36 support

[richm]

community.general version 12 has dropped support for py27 and py36 - ensure that
the roles do not install/use this version - see
ansible-collections/community.general#582

By default, installation will get the latest 11.x version. The lower bound
6.6.0 is an older version, but I don't want to restrict the ability of a user
of a particular role to use an old version, rather than forcing them to use
11.x or later. Some roles like rhc explicitly require 6.6.0 or later - I
think this is a reasonable lower bound for all roles.If a role needs a different
version, the role can define its own community_general_version in the role's
host_vars file in .github.

Standardize file format across all roles for consistency and ease of updating

This update may remove the SPDX license information from the file - this is ok -
the role/project already has a license, this file is trivial, and many
requirements files do not have the license header anyway.
