apt-key is deprecated

[killrazor]

When using https://cpkg.datto.com/getLinuxAgent.txt with Debian 11+ or Ubuntu 22.04+

Not sure that I have the correct package here but running the code listed above produces a warning like:
W: https://cpkg.datto.com/datto-deb/public/jammy/dists/jammy/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details

Can you please add in a lil check for os version and remedy the use of a deprecated function?

Okay, will fix that. Thanks.
