deprecated with_items use loop instead

[e30chris]

[DEPRECATION WARNING]: Invoking "homebrew" only once while using a loop via squash_actions is deprecated. Instead of using a 
loop to supply multiple items and specifying `name: "{{ item }}"`, please use `name: ['corectl', 'coreutils', 'cowsay', 'curl',
 'dnstracer', 'exiftool', 'git', 'git-lfs', 'gnu-getopt', 'gnu-sed', 'gnu-tar', 'gnu-time', 'gnu-units', 'gnu-which', 'gnupg', 
'gnupg2', 'gnutls', 'htop', 'htop-osx', 'hugo', 'iftop', 'jpeg', 'jq', 'moreutils', 'mtr', 'mutt', 'nmap', 'openssl', 'opus', 
'p7zip', 'packer', 'prettyping', 'progress', 'readline', 'rename', 'siege', 'ssh-copy-id', 'sysdig', 'terraform', 'tldr', 
'tree', 'unrar', 'vim', 'watch', 'wget', 'wireshark', 'xz', 'youtube-dl', 'zsh-completions', 'zsh-syntax-highlighting']` and 
remove the loop. This feature will be removed in version 2.11. Deprecation warnings can be disabled by setting 
deprecation_warnings=False in ansible.cfg.
