📦 Move to React 19 and update peerDependencies

[rowanc1]

This disables storybook for now by (1) removing it from the npm workspace and (2) moving the github workflow out of the right place.

Now that we have the myst-theme docs, I think storybook might be a bunch less useful, and perhaps we just simplify and remove it rather than keeping it alive?

I can confirm that the preview both works and is on React 19.1.0.

IIRC jupyter deps might be loading react 18? Did you test case include any jupyter outputs? Jupyter-book/example-outputs might be helpful for testing

[stevejpurves]

would love to see React 19 come in but did anyone test with jupyter outputs in the mix here? and with in page execution? or is that still a todo?

[stefanv]

Are these test procedures / requirements outlined in a doc somewhere? It would be useful for future upgrades to have a checklist.
