Deprecate standalone homebrew and mas roles after collection is working

[geerlingguy]

This will be a TODO until I have geerlingguy.homebrew and geerlingguy.mas fully incorporated into this collection, and have a release I'm happy with. At that point I'll close all issues in those repos, update their READMEs and project descriptions to mention this new collection, and archive them, and then mark them as deprecated on Ansible Galaxy itself.

The roles are incorporated, and this collection's had a few releases. It is time to make the switch.

Issues for:

• Homebrew: Deprecate this role in favor of the new geerlingguy.mac collection ansible-role-homebrew#166
• MAS: Deprecate this role in favor of the new geerlingguy.mac collection ansible-role-mas#31

Done!
