Adding React 18 to the peerDependencies

Adding React 18 into the mix as the dependencies were locked to v16 or v17. I got the following error when trying to install the module on a NextJS React 18 project

```
> npm install --save moment react-moment
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
