Update for React 18 support

[therealchewbecca]

Please add support for React 18. Are there plans to update any time soon?

I see someone already opened a PR #189 and deployed their fork to npm as react-18-input-autosize

Has anyone figured out how to apply the typescript definitions to the react-18-input-autosize fork?

Struggled with this for awhile, ended up abandoning react-input-autosize and wrote a simple component for my usecase
