Uh oh, the pin didn't work it still downloaded pyo3-0.23.4

[ryanking13]

Probably we need pyodide/pyodide-build#49 (comment)?

Otherwise, we can set PIP_CONSTAINT env variable globally in CI.

I think the latter is the better option, as pyodide/pyodide-build#49 only applies to in-tree build.

Can you make a PR to fix it @ryanking13?

[hoodmane]

Or maybe we should stop being obstinate and just bump the rust version...

Sure, let me try.

Thanks!

Oh, I just realized that pyo3 is not a Python package, but it is a rust package 😅. Anyway, let me try to fix this.

I think this will work (tested locally) #5325.

We are using the same approach for cbor-diag

Yes, that looks like a better solution. Thanks, @ryanking13!
