Replaces anaconda python installation with miniforge

[dpshelio]

Due to the anaconda ToS changes, using conda-forge avoids that learners may be in breach of the ToS after they leave the workshop. This has been discussed in Carpentries #genral Slack and a pip alternative is provided at #837.

It provides instructions to create a swc environment is created with the basic needs for the workshops (includes explicitly both numpy for the inflammation lesson and pandas for the gapminder).

This, however, has the added difficulty to require that learners change environment (conda activate swc) and start jupyter from the terminal and not from a launcher (as anaconda provides for Windows and macOS).

I've tried to find up a way to get jupyter installed in the base env, and provide instructions to create a shortcut, but it becomes too cumbersome, plus it would only benefit Windows users. A comment has been left there to inform future attempts.

@dpshelio Given our workshops generally teach basic shell CLI (using git-bash on Windows, Terminal on MacOS, bash on Linux), I think it's OK to ask people to launch jupyter lab from the CLI. That also makes sure their CWD is in the "right" place vs. having to show them how to navigate back to their Desktop in Windows when using the launcher.

@n2ygk I also think it's not too much of a cognitive load to launch from the terminal, and it also avoids the problem we've encountered a few times with Windows where learners don't recognise the directories Jupyter is showing (normally on computers that got two user directory structure due to onedrive, and Jupyter opening the "standard" user profile and not the one the user is familiar with which normally is onedrive's).

Thank you for submitting this @dpshelio. We established a task force to update the lesson setup instructions, and I would like to wait until that group has had time to consider the various different options, before implementing any change. The task force's decision will be made in the next month or so.
