Support pyodide 0.26.0

[bollwyvl]

Problem

Pyodide 0.26.0 was released.

Proposed Solution

• add to 0.3.2
• add to forthcoming 0.4.0
• both?

Additional context

There are a number of breaking changes. I haven't yet explored what impact they will have.

Of note:

• now based on cpython 3.12.1
• ipython and its novel dependencies (traitlets, prompt-tool-kit), are now in the base pyodide distribution's pyodide-lock.json. This is probably very good, but no telling what it will reveal

#113 is up, no showstoppers on RTD.

Closing as fixed by #113, thanks!

• add to 0.3.2

Maybe we can skip releasing this in a 0.3.x, if we get 0.4.0 out in the coming days?

[bollwyvl]

fine either way. it's hard to know if there are folk that are using the components of this kernel that would want 0.26.0 and py312, but not want, e.g. #114
