Investigate using debug builds of pyodide

### Problem

Sometimes it's hard to debug pyodide issues: apparently the debug instance can be used

### Proposed Solution

From the Workshop:

```
https://cdn.jsdelivr.net/pyodide/v0.22.0a3/debug/pyodide.asm.wasm
https://cdn.jsdelivr.net/pyodide/v0.22.0a3/debug/pyodide.asm.js
write over node_modules/pyodide/*
```

### Additional context

So theoretically, we can just set the URL to a different one and get debug builds (maybe worth it on the RTD site) and/or use it when an offline pyodide is forced.
