task(RHOAIENG-33045): Update Runtime image SHAs for PY312

What changes have been made

Updated CodeFlare SDK runtime image defaults to include the new Python 3.12 image. This has also been updated in the demo notebooks where referenced.

Additionally, I've moved our supported versions logic to constants.py as I feel this is a more intuitively central location for this. Similarly, a new utils.py file extracts the correct runtime image version to pull in place of the less central existing logic.

Verification steps

• Checkout this branch.
• Build the whl file by running poetry build.
• Open any demo notebook and set the kernel to a Python 3.12 version.
• Install this version of the SDK by running pip install <path_to_your_whl> --force-reinstall
• Restart the kernel.
• Create a Ray Cluster.
• Check the head pod spec for the image tag or log in to its terminal and run python3 --version to verify that it is using Python 3.12.9.
• Repeat the above with a kernel set to Python 3.11 to verify that the old image is also used as needed.

Checks

• I've made sure the tests are passing.
• Testing Strategy
  • Unit tests
  • Manual tests
  • Testing is not required for this change

E2E has failed due to an assertion in the local_interactive_sdk_kind_test. The move to Python 3.12 has introduced a slight computational deviation which causes the assertion to fail. See the difference below.

assert 1789.4644387076728 == 1789.4644387076714

Given just how small the difference is, allowing a more approximate value might be a better solution than a hard-coded one.

[chipspeak]

I've gotten the same error multiple times with the same 0.0000000000008% difference in the assertion. I've updated the value to match the Python 3.12 difference just to see if the tests pass etc. I don't think there'd be any harm in keeping this new value as we won't need to test Python 3.11 in this test going forward.

great improvements to the runtime image selection thanks Pat, lgtm
