Update to Python 3.10, fix GitHub workflow and automated tests

[martinburchell]

• Update to Python 3.10, which is the oldest supported version
• Update Python packages
• Update Postgres in CI workflow to 14, which is the oldest supported version
• Fix the CI scripts so they can be run locally
• Don't try to support curl and wget as wget is assumed to be present elsewhere
• Use Postgres over TCP not Unix socket as this is assumed elsewhere
• Fix failing tests by replacing exact match XML comparison with checking specific nodes. There is scope for further optimisation here as there is a lot of duplication in the tests.

Note that the CI script is currently set up to work with the Intermine fork at https://github.com/ucam-department-of-psychiatry/intermine.git, build-workflows branch. We can update that once it is merged.
