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.

When will this PR be merged? @clem9669
I'm getting failing builds for installing docker on Kali via this role due to the wrong url getting set for this task: https://github.com/geerlingguy/ansible-role-docker/blob/master/tasks/setup-Debian.yml#L40

this causes it to fall back to attempting to download docker gpg key from a non-existent url "https://download.docker.com/linux/kali/gpg" and piping it to the now deprecated apt-key command.
starting at Debian 11 and Ubuntu 20.10, apt-key is now deprecated and it will no longer be available after Debian 11 and Ubuntu 22.04
