fix: Specify react and rxjs in peerDependencies

[raon0211]

Dependencies should be specified in either dependencies or peerDependencies section of package.json when accessed in production code via import statements or requires. It seems that although rxjs-hooks is importing react and rxjs in its production code, neither of them is specified.

Below is a part of the production bundle where rxjs and react is imported. (dist/esm/use-event-callback.js)

This makes the library to break in environments using strict dependency management systems such as yarn v2.

This pull request fixes the issue by specifying react and rxjs in peerDependencies of package.json.
