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.

Summary by Sourcery

Restrict community.general to compatible versions by default and standardize requirements file management

Bug Fixes:

• Prevent installation of community.general v12 which drops Python 2.7/3.6 support

Enhancements:

• Default to latest 11.x (with a lower bound of 6.6.0) for community.general and allow per-role overrides via host_vars
• Standardize collection-requirements.yml format across roles with a managed "DO NOT EDIT" header, removing SPDX boilerplate

Reviewer's Guide

This PR enforces Python compatibility by pinning the community.general collection to versions >=6.6.0,<12.0.0 across all roles, introduces a standardized header for managed requirement files, and retains per-role override support.
