Pydantic ImportString can report the incorrect missing file

[julianstirling]

Pydantic ImportString responds with the wrong missing file if there is an import error. This is an upstream pydantic bug : pydantic/pydantic#12715

The upstream bug is fixed. We are now waiting for the Pydantic 2.13 release for this fix to be release.

Note The original text for this issue was unclear it also talked about the 2.10->2.12 upgrade. This has now been done by #285.

Just because I've read this incorrectly at least three times, this issue means that we should increment the dependency on Pydantic as soon as 2.13 is released, so that we get the fix. We cannot do anything about this now, because the fix isn't released yet.

#285 updates a number of dependencies. Prior to #285 the tests (with pinned dependencies) used an older version of pydantic than 2.12. Updating pydantic in the pinned dependencies gave some deprecation warnings, which #285 fixes. I don't see those warnings in the tests with unpinned dependencies from code prior to #285, so I guess one of the pyproject.toml changes must have allowed an upgrade that introduced them. #287 now logs package versions in CI test runs, which should really help debug this sort of thing in the future.

Hopefully this will reduce the impact of requiring an update to 2.13, when it comes.

The OpenFlexure Microscope does not pin its dependencies in either testing or production at present, so it was already on the newest pydantic (2.12).

Sorry, yes, this issue was badly phrased. Moving to pydantic 2.12 will make it easier to move to 2.13. I'll edit this issue to be clearer.
