Switch from Ubuntu 20.04 LTS to 22.04 LTS for jobs

See here:

• Why does build.yaml test-sim test only the rv64gc/lp64d bare-metal/newlib toolchain? #1351 (comment)

Switch from Ubuntu 20.04 LTS to 22.04 LTS for jobs build (make report step), test-sim and build-multilib.

Note that build-multilib is disabled by default so would need to be temporarily enabled in order to validate this change:

• riscv-gnu-toolchain/.github/workflows/build.yaml

  Line 123 in 6b13243

  if: ${{ false }} # Disable until multilib errors are triaged

LGTM, let's see what the CI says.

This LGTM as well. A side note on testing multilib - It currently times out (>6 hrs) on github runners.
It may be possible to only test some of the multilib targets using #1293, but I haven't used that option before so I'm unsure of how it works.

@TommyMurphyTM1234: you need to fetch the latest changes (your Ubuntu PR), rebase this commit and force-push to your workflow-jobs topic branch.

Sorry about that - I think that it's resolved now?

Merged.
Thanks!
