minor cleanup

[jrgirvan]

I found myself in a similar situation with a fresh install of popos, though due to a failed kernel update forcing me to reinstall from scratch. (turns out that was just a a skill issue and the new kernel not supporting my graphics card)

i3.yml

• sur5r provides their key as a deb, so can't improve the download, if they provided it as a gpg key, we could use the apt_key built in
• use the built in apt command for installing the deb file
• use the built in apt_repository for added the repository
• use the ansible variable ansible_distribution_release to fetch the distribution release name

zsh.yml

• use vars.yml file for variables
• update comment on change shell task

common.yml

• replace apt, with ansible.builtin.apt
• replace loop (not working), with pkg, which takes a list of packages
