Support React 19

[ChristianMurphy]

Is your feature request related to a problem? Please describe.

I'd like to upgrade my project to use React 19, now a stable release: https://react.dev/blog/2024/12/05/react-19

This is currently blocked by a peer dependency allowing up-to, but not past React 18

storybook-addon-remix-react-router/package.json

Lines 75 to 76 in 3343530

	"react": "^16.8.0 || ^17.0.0 || ^18.0.0",
	"react-dom": "^16.8.0 || ^17.0.0 || ^18.0.0",

Describe the solution you'd like
Project to be tested with React 19, and add React 19 to the version range.

Describe alternatives you've considered
Wait to upgrade, or don't support React 19.

Additional context

Storybook does not support React 19 yet.

See storybookjs/storybook#29805

It does though.

You should be able to use Storybook with React 19, but if you found any inconsistency or unsupported feature, please let us know in this issue.

It is a call for feedback, not a statement of non-support.
