React 18 support

[TJ09]

🐛 Bug Report

According to npm, fbt declares a peer dependency on react that ranges from 0.12.0 - 17.x.x. This means it is not possible to adopt React 18 in a project that uses FBT, though in my own testing, forcing npm to install conflicting versions seems to work just fine anyway.

To Reproduce

$ npm init
...
$ npm i react@18.0
$ npm i fbt

Expected behavior

fbt is installed successfully.

Actual behavior

$ npm i react@18.0
