Update software versions used in CI

The ubuntu-20.04 runner is due to be deprecated on 2025-02-01 and unsupported by 2025-04-01.

The previous version of the metadata validator wouldn't run on Ubuntu 24.04 due to a dependency version mismatch, so has been updated.

The actions/checkout and actions/setup-node actions have also been updated to their latest major versions.

The version of Node.js used has been updated to the latest LTS version.

The version of Python used has been updated to the latest minor version.
