`conda` / `mamba` / `micromamba` package managers do not exist

🐛 Bug

The conda / mamba / micromamba package managers are missing. There seems to be a pretty old mamba existing on the system, but it does not work for me! (eg. simple arguments such as -y do not seem to exist on it). Due to this, pacakges deployed in conda-forge cannot be used anymore (unless the user installs a package manager by themselves - which does not sound like a good solution to me).

To Reproduce

A simple version check should do the trick:

• !conda --version (returns command not found error)
• !mamba --version (this is the only one which returns 0.11.3, a pretty old version)
• !micromamba --version (returns command not found error)

Expected behavior

It would be nice to be able to create and maintain conda environments for users. I see there was some micromamba setup a few months back, but seems like it's been rolled back in the latest image.

Additional context

From my recollection, this used to work a few months ago. I am not sure when it got discontinued.

In case someone stumbles upon this, my current workaround is to install condacolab via pip and use it for installing conda packages.
