Support for React 19 / Next.js latest version

[Bernardoow]

Hi, I'm trying to create a proof of concept using the latest version of Next.js, react-admin, and react-admin-firebase.

However, I ran into a problem: the react-admin-firebase package currently only supports React versions 17 and 18. Since the latest version of Next.js uses React 19, the peer dependency restriction causes installation or runtime errors.

Would it be possible to update the peer dependencies to allow React 19 as well?

Thanks in advance!
