chore: update react version

[YvesRijckaert]

Update react version to 19

[MarcelSchulz]

We just ran into an issue that seems to have been caused by this upgrade. We did not have the live-preview version pinned to .15 while we were still on Next 14 & React 18 and after that we ran into build-breaking errors seemingly caused by the LivePreviewProvider.
Doesn't this now require react 19 for all projects using this library?

[YvesRijckaert]

@MarcelSchulz Thanks for your feedback, the peerDependencies are still set to allow other (lower) versions of react:
"react": "^17.0.0 || ^18.0.0 || ^19.0.0" So I would not expect that 🤔
Could you elaborate on the issue you encountered?

[MarcelSchulz]

Not as precise as I would like to but these are the traces we get:
This started happening at 1 PM GMT+1 today and is resolved by either upgrading next 15/react 19 or removing the library (or downgrading to .15), so I suspect this must be correlated.

app-index.js:33 The above error occurred in the <NotFoundErrorBoundary> component:

React will try to recreate this component tree from scratch using the error boundary you provided, ReactDevOverlay.

Thanks for the context @MarcelSchulz
I'll do a revert for now and investigate a bit further
