Unsupported distribution linuxmint 21.3

proposed working fix (patched version zerotier_installer.sh.txt):

VERSION_ID=$(echo $VERSION_ID | cut -d . -f 1)

I could not find the installer script in the repo. Therefore no pull request.

install script is here: https://github.com/zerotier/install.zerotier.com/blob/main/install.sh.in
