Using an editable installation of Kayobe fails on Rocky Linux 9 or
Ubuntu with an error such as:

    ERROR! The requirements file '/home/rocky/kayobe/kayobe/requirements.yml' does not exist.
    Failed to install Ansible roles from /home/rocky/kayobe/kayobe/utils.py/../requirements.yml via Ansible Galaxy: returncode 1
    Control host bootstrap failed - likely Ansible Galaxy flakiness. Sleeping 5 seconds before retrying

This is caused by recent changes to how pip manages editable
installations. The egg-link file that Kayobe was using to find the
source path does not exist anymore. Instead, there is a direct_url.json
file under the kayobe dist-info directory that can be parsed.
