Update dependencies to React v18.x

The library is great but currently it seems to rely on the following dependencies:
```
    "react": "^16.8.0  || ^17.0.0",
    "react-dom": "^16.8.0  || ^17.0.0"
```
@iamyoki Could you upgrade dependencies so it also supports React v18? It works out the box but just need to add:
```
    "react": "^16.8.0  || ^17.0.0  || ^18.0.0",
    "react-dom": "^16.8.0  || ^17.0.0  || ^18.0.0"
```
