Update variables to support Kali Linux

[straysheep-dev]

After seeing how Pop!_OS and Linux Mint were supported, it looks like the same can be done for Kali using a separate variable for the release string here:

docker_apt_ansible_distribution_release: "{{ 'bookworm' if ansible_distribution in ['Kali'] else ansible_distribution_release }}"

...and replacing the few instances of ansible_distribution_release with that new variable.

There may be a better way to do this since bookworm will need updated with each Debian major release. However it's infrequent enough that it may be acceptable for now, similar to the GPG key checksum being a static value.
