build(deps): Update RustPython to 0.3.1

[youknowone]

#3063 draft

The code part looks done, but I believe @discord9 wants to change the dependency to the GC version.

@youknowone welcome! Thanks for driving this effort.

Really thank you for your effort, havin't found enough time to upgrade rustpython depend! I should very soon be able to switch to a GC-ed fork (although it's still bugged with at least one bug of method monkey-patch cause use-after-free could be due to some complex ref cycle, and I need to write something like obj-graph to found out about it), but at least it can pass those tests and not cause memory leak if not using too pythonic code...

We may move forward the GC support upstream and then upgrade RustPython version in GreptimeDB.

Thank @youknowone for your demostration, I successfully upgrade the parser part in another patch now. We'll pick up this patch once the RustPython upstream is in a state upgradable for GreptimeDB.

Closing for now since it won't have progress until then.
