React 18 support

[mike-dean-talis]

Is your feature request related to a problem? Please describe. react-fontawesome doesn't seem to support React 18, which is currently in RC2.

Additional context Currently, updating package.json to 18.0.0-rc2 produces the following npm error.

I just started a new React 18 RC3 project and got surprised by this too. Hoping it gets supported soon!

Since you are using a pre-release version the version spec we have "react": ">=16.x" doesn't include pre-releases. Can you use --force?

I'm also getting this error with primereact -

I can't install or uninstall anything either.

And now React 18.0.0 has been released, so it isn't a pre-release version.

I'll close then. @mike-dean-talis if you are still having issues let me know.
