feature: Bumping Pyodide version or allow specifying pyodide version to use

[ahuang11]

Is your feature request related to a problem? Please describe.

I want to install Panel with pyodide

import micropip

bk_whl = "https://cdn.holoviz.org/panel/1.5.4/dist/wheels/bokeh-3.6.1-py3-none-any.whl"
pn_whl = "https://cdn.holoviz.org/panel/1.5.4/dist/wheels/panel-1.5.4-py3-none-any.whl"
await micropip.install([bk_whl, pn_whl])

However, I encounter

PythonError: Traceback (most recent call last):

See: https://pyodide.org/en/stable/usage/faq.html#micropip-can-t-find-a-pure-python-wheel
You can use `micropip.install(..., keep_going=True)`to get a list of all packages with missing wheels.

Describe the solution you'd like

I believe it's a pyodide version mismatch because it works on https://pyodide.org/en/stable/console.html

Describe alternatives you've considered

Additional context

Panel has its own custom Pyodide implementation but would like to use mkdocs for panel-extensions https://panel.holoviz.org/tutorials/basic/size.html

Hi @ahuang11, thanks for the request! I'd be open to an option that lets users pick a Pyodide version. In the meantime we can also upgrade the hardcoded version in the formatters/pyodide.py module.

Would you like to send a PR for the latter, or both 🙂?

[ahuang11]

Thanks for the quick response! I'd be happy to create a PR for both.

For customizing Pyodide version, I think it's just a matter of checking whether pyodide_version is in options, and if so, formatting this right?
