Fix CI deprecation notices (#385)

* Remove set-output, use GITHUB_OUTPUT instead, as per deprecation notice. Should resolve #172

* Remove unnecessary whitespace

* Bump Ubuntu version to 22.04

* Update cache & checkout actions to v4 (latest at time of writing)

* Update setup-python to v5 (latest), change python version to 3.10 (default for Ubuntu 22.04)
