Fix #562

ansible-lint 6.19.0 started complaining about this:

   schema[tasks]: 'become_method' must be one of the currently available
   values: ansible.builtin.runas, ansible.builtin.su,
           ansible.builtin.sudo, ansible.netcommon.enable,
           community.general.doas, community.general.dzdo,
           community.general.ksu, community.general.machinectl,
           community.general.pbrun, community.general.pfexec,
           community.general.pmrun, community.general.sesu,
           community.general.sudosu, containers.podman.podman_unshare

Fixes: 26f289b7 ("Capitalize the first letter of all task names")

This adds a collaborative markdown editor as newly offered service which
is available via login for all Arch Linux Staff with an option to allow
anonymous edits by users (not default). Users are managed via keycloak
and require the Staff role to be allowed in, non staff keycloak users
currently will receive an internal server error due to an upstream
issue.
