Include information about 'miniforge' in the docs

I came across 'miniforge' while reading Wolf's blog on mamba.

I found the miniforge repository of conda-forge. Here: https://github.com/conda-forge/miniforge

There is a README.md file with some information about miniforge. Mostly installing and downloading steps and commands.
(https://github.com/conda-forge/miniforge#readme)

Maybe we need to add some information about miniforge in the main conda-forge docs too. Or atleast mentioning it somewhere and adding a link to that README file. (I don't know if that's already done?)

There is a small note added about 'miniforge' in the brief introduction page of the conda-forge docs.
Just above this: https://conda-forge.org/docs/user/introduction.html#display-conda-forge-packages-in-anaconda-navigator

Is that sufficient?
