Add a section for Ansible Semaphore?

See: https://www.ansible-semaphore.com

A very slick, completely open-source UI for Ansible that is a heck of a lot easier to deploy than AWX, if your needs are met by it.

Start by reviewing the Ansible Semaphore site linked in the issue, then locate the repository's existing documentation or book section covering Ansible interfaces. Add a section describing Semaphore as an open-source UI and its deployment advantage over AWX, keeping the scope consistent with nearby material. Done means the section is present and accurately reflects the linked project.
