*What would you like to be added*:

Allow for `includes` when defining a custom service (https://firewalld.org/documentation/man-pages/firewalld.service.html), e.g.

```yml

• name: Run firewall role
  ansible.builtin.include_role:
  name: fedora.linux_system_roles.firewall
  vars:
  firewall_disable_conflicting_services: true
  firewall:
• service: custom
  short: Custom
  description: Custom service
  port: 2222/tcp
  includes: [http, https]
  state: present
  permanent: true
  ```

Currently `includes` are silently ignored.

An example is e.g. the predefined firewalld service `freeipa-4` (https://github.com/firewalld/firewalld/blob/main/config/services/freeipa-4.xml)

*Why is this needed*:

This makes firewalld services more explicit and easier / quicker to read when there are many non-standard ports.
