Issue Resolved / Feature Added

React 19 Beta has been released on 25th April.
And RC has been released on 15th May.
We'd like to apply React19 RC to enact.

Resolution

Upgrade to React 19

Additional Considerations

• For updating react 19, @storybook/addons needs to be updated v7.6.0 or higher version.
  -> I temporary update react 19 with npm install --force option but I think it's needs to be discuss.

LGTM
Note that we have failing unit tests since testing-library does not support React19 as of now.
npm install --force should be fixed once storybook supports React19.
