Update conda create instruction to 3.9.0

[gr1010]

Describe the bug
Currently the installation instruction has the line:
conda create -n simplefoc python=3.6.0.

Python 3.6 is now unsupported by Anaconda, so this line results in an error.
JorgeMaker's Github repo has been updated with the instruction:
conda create -n simplefoc python=3.9.0

Perhaps this page should have the same update.

To Reproduce
Steps to reproduce the behavior:
Follow installation instructions from https://docs.simplefoc.com/studio
conda create -n simplefoc python=3.6.0.
See error.
