The current doc use homebrew/cask-cask instructions, and cask was changed.

The current instructions to install java with Homebrew doesn't work, and mysteriously it requests your github email and password 🤔🏴‍☠️.
This PR change the docs to install java using https://github.com/AdoptOpenJDK/homebrew-openjdk with correct cask command in homebrew.

Not sure why CI is not triggered :(
Can you try to force push to trigger it?

[Lcsmarcal]

@KapJI It's happening with another PRs too :(

[narlei]

I tried force push but still not triggering the CI. As @Lcsmarcal says, It's happening with other PRs too.

@narlei Thanks a lot for figuring this out! CircleCI is very confusing.

We probably should migrate to Github Actions but these CI definitions are large and we need someone to do that.
