44b7b9a3 - uv/tests: tweak marker emitting tests to use Python 3.12.1

uv/tests: tweak marker emitting tests to use Python 3.12.1 The test output seems to depend on using Python 3.12.1 specifically. While I'm not sure how it happens, it seems like these can get out of sync between CI and local testing. In this case, I had a problem where the marker expressions emitted locally were tied to Python 3.12.4, but the tests in CI were tied to Python 3.12.1. Changing the test to require 3.12.1 specifically fixes this.
