React 19 support

[bisswanger]

Provide a general summary of the feature here

react-spectrum S2 has been released as final release 1.0.0
While we have it working with React 18, it specifies a React 19 peerDependency

Trying to upgrade to React 19 currently fails using react-spectrum-charts. (when removing all charts, our app is working fine using react 19)

We are seeing following error

can't access property "ReactCurrentOwner", r.__SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED is undefined

We have a major version update (2.0) in progress, which will include initial Spectrum 2 support. We're going to perform this upgrade alongside that version bump.
