WAPM Homebrew formula

[alexreg]

This is just a note that I created a macOS Homebrew formula for wapm (naturally named wapm), and this got merged today, so it's now available. Maybe you can put it in one of your guides (or not, no big deal).

Thanks!

@Hywan you have the most context on Homebrew at Wasmer I believe, pinging to let you know and in case you have any input.

I'll leave this issue open as a reminder to update the docs!
