Rework documentation to use Miniforge instead of Anaconda

[wwarriner]

What is inaccurate?

We need to migrate RC from Anaconda to Miniforge due to changes in the Anaconda Terms of Service precluding use by any organization larger than 200 employees.

Hence all documentation related to Anaconda must be changed to reference and make use of Miniforge instead.

Where is the inaccuracy?

Please add locations in the comments and we will compile them in this issue.

• https://docs.rc.uab.edu/workflow_solutions/using_anaconda/#good-practice-for-finding-software-packages-on-anaconda needs heavy rewriting to get away from Anaconda. It should maybe become a separate tutorial!
• https://docs.rc.uab.edu/workflow_solutions/getting_containers/#create-your-own-docker-container needs rewriting to avoid usage of miniconda. There may be other uses in that file.

Useful boilerplate
