[Opm] First release candidate ready for 2022.10

[Atgeirr Rasmussen]

Dear all,

The rc1 release candidate for the upcoming release is ready for testing!

You can check out the release candidate from the github repos using the tag

      release/2022.10/rc1

or use binary packages for Ubuntu Linux versions 20.04 and 22.04.
To test the binary packages, follow the normal installation instructions at the OPM website,
but replace the command

      sudo apt-add-repository ppa:opm/ppa

with the command

      sudo apt-add-repository ppa:opm/testing

to use the testing package repository instead of the regular one.
