DOC - contribution setup guidelines need improvement

[kaycebasques]

Hi, I hit some friction when setting up my local development environment on Debian-based gLinux. I used the Get started guide.

# easier for me to do everything from virtual env. not really discussed in the guide.
python3 -m venv venv
source venv/bin/activate
python3 -m pip install tox
python -m pip install pre-commit
# installing pandoc over pip didn't work. had to install system-wide.
sudo apt install pandoc
# ditto.
python3 -m pip install graphviz
# got some warnings-as-errors about files already existing in _build, see below.
rm -rf docs/_build
tox run -e docs-dev

the warnings:

The HTML pages are in docs/_build/html.
docs-dev: commands[1]> python tests/utils/check_warnings.py

there's also a bunch of images and stubs not found but I guess I can ignore these?

eHi @kaycebasques, thanks for contributing to PST.

installing pandoc over pip didn't work. had to install system-wide.

In the guide - Install your tools - we add pandoc as a pre-requisite, perhaps should note this should be installed system-wide

ditto.
python3 -m pip install graphviz

Same, I think we need to add a note about installing this (it was recently added, so it seems like it was missed)

I need to check the stubs warnings, but they can be safely ignored. However, the documentation could be tweaked overall to better support contributors.

FYI I updated the issue title to reflect the changes needed a bit better
