Relay Compiler & Relay LSP broken on latest watchman on homebrew

Hey,

TLDR: do not install the latest version of watchman on homebrew.

The latest version of watchman published on the homebrew repository, is currently not working, and failing out due to various issues that can be seen here: https://github.com/facebook/watchman/issues/1264.

I understand that watchman published on homebrew is a community effort, but sadly that has been stuck in trying to get the latest versions to work. (as seen here: https://github.com/Homebrew/homebrew-core/pull/201422).

I have also tried to to install a previous version of watchman on homebrew, but that fails on building.

I have also tried to build the project from source, but again that has failed due to `folly` exceptions.

I'm currently running on WSL2 hardware, and have 0 issues with relay until now, and it looks like relay heavily depends on watchman for a smooth developer experience.

Any help would be appreciated, l realise that this is not specifically a relay issue, however this does heavily impact the local development environment.
