Match python and cpp arrow versions

[jleibs]

Although in theory there shouldn't be a hard link between versions of arrow across our different languages, the arrow conda projects seem to make libarrow and arrow-cpp require the same version. This means if rerun-cpp needs a different version of arrow that rerun-py we can't use both in the same conda package.

Specifically this prevents us from having a pixi project which includes arrow-cpp and also rerun-sdk to streamline launching via spawn

Note that supporting Python 3.12 (#3699 ) will require PyArrow 14.

we match cpp & arrow by now!
