PIXL pipeline: Update python version to 3.12

[stefpiatek]

Definition of Done / Acceptance Criteria

To maintain python support during life of PIXL project.

PIXL modules currently running on python 3.9 and 3.10. Should update these to 3.12 where we can.

Sadly orthanc seems to be always have Docker containers with 3.9 so may need to accept that for now in pixl_dcmd

Testing

Tests pass, and carry out a test run on the GAE

• core
• cli
• ehr-api
• imaging-api
• pixl_dcmd (Orthanc still requires 3.9)
• hasher
• pytest-pixl
• system-test
• Test run on GAE

Details and Comments

• Update pydantic to latest version and replace validator with field_validator

As part of #309, we're using pydantic.validator, however in pydantic>=2.0 the recommended method is to use pydantic.field_validator.

PyYAML 6.0 gives installation errors on 3.12.
Do we still need PyYAML though? If yes, should increase version requirement to 6.0.1

[stefpiatek]

I think yeah we do need it actually, let's update to 6.0.1

[jstutters]

#267 solves the PyYAML problem but can't do anything about the Python version bundled with the Orthanc Docker image which acts as a constraint on pixl_core and pixl_dcmd.

orthancteam/orthanc has been documented as the successor to osimis/orthanc which is no longer being updated. Still python 3.9.2 but hopefully that should mean there'll be newer releases soon
