our pinned orjson has no python3.12 wheels and needs to be built locally with Rust

This is with python 3.12.0 on a new fedora 39 machine.

edit: so the problem here is that the pinend orjson version

api/requirements.txt

Line 18 in 8fa6be3

orjson==3.8.6

does not have wheels for python3.12 on pypi - makes sense, 3.12 wasn't released then. But this means I need the local build dependencies.

We should test that our builds succeed on newer python versions so we can detect this automatically and bump the versions accordingly.

See e.g. here: neurobagel/planning#23
