Upgrade ci to use ubuntu 22 04 (#1427)

* Refactored get_collection_coverage tests

Using pytest's parametrize mark. This makes it easier to isolate test cases in order to fix the errors that are showing up when running under Python3.8

* Add Python 3.8 to the CI matrix

* Reverted tests back to non-parametrized form

* Dropped Python 3.7 from main github CI workflow

* replaced ubuntu 20.04 with ubuntu 22.04 in CI workflow files
