Upgrade to Ubuntu 22.04 LTS

[master-bob]

Upgrade to use hopefully use a later version of ruby by default allowing for latest bundler to be used. Using 20.04 causes bundler to fail to install due to Ruby 2.7 being used instead of the required 3.0.

The Ruby error, pulled from this build, is:

Once this is accepted, I will reopen #162 and #163 based on 22.
