Getting mamba command not found with Homebrew installation

Issue

I checked the README and installed miniforge with brew install miniforge. After installation, I tried to create an environment with mamba create -n testenv and I get zsh: command not found: mamba. I tried where mamba and I got mamba not found. Not sure if I should use Mambaforge distribution? But the Mamba Installation Guide suggested to use Miniforge unless the older version of Mamba is needed.

You could open a pull request at homebrew-cask to add, after this line: https://github.com/Homebrew/homebrew-cask/blob/ec3676bc89f158f7d06c96e3cd1b5dfb41dbe0ed/Casks/m/miniforge.rb#L27

the same thing for the mamba executable, i.e.:

binary "#{caskroom_path}/base/condabin/conda"
binary "#{caskroom_path}/base/condabin/mamba"

Thank you, @fxcoudert. I've tried conda init zsh after installing miniforge with homebrew and this also worked.
