Change the metadata format

[woxtu]

Hi,

This PR changes the metadata format written in <py-config> tag.

The current metadata format is like this:

# from https://github.com/pyscript/pyscript/blob/48e6b1a84efb0d41609258b0c2b5b525ca571719/docs/tutorials/getting-started.md#the-py-config-tag
- autoclose_loader: false
- runtimes:
  -
    src: "https://cdn.jsdelivr.net/pyodide/v0.20.0/full/pyodide.js"
    name: pyodide-0.20
    lang: python

Representing it as JSON is like this:

[
  {
    "autoclose_loader": false
  },
  {
    "runtimes": [
      {
        "src": "https://cdn.jsdelivr.net/pyodide/v0.20.0/full/pyodide.js",
        "name": "pyodide-0.20",
        "lang": "python"
      }
    ]
  }
]

I think this should be like this:

autoclose_loader: false
runtimes:
  - src: "https://cdn.jsdelivr.net/pyodide/v0.20.0/full/pyodide.js"
    name: pyodide-0.20
    lang: python

Representing it as JSON is like this:

{
  "autoclose_loader": false,
  "runtimes": [
    {
      "src": "https://cdn.jsdelivr.net/pyodide/v0.20.0/full/pyodide.js",
      "name": "pyodide-0.20",
      "lang": "python"
    }
  ]
}

Yup. This should have been right format. Thanks for the catch @woxtu !🎉

@pww217 CI is failing because it should test the examples against the newly built artifact, not against pyscript.net. Any ideas?

Hey seems like this can be merged!
I've fixed the conflicts locally already, but thought I should ask if it's okay for me to force push it here?
@woxtu feel free to fix it locally and push it yourself if you prefer.
Thank you for the work! 🌸

The docs review will still fail but the build latest should success with #433 and #435 merged. Thanks @marimeireles!

@marimeireles Thanks! It's okay to push yours.
