Documentation overhaul - Fixing formatting issues, autodoc implementation, and added variables for versions. (#3734)

Closes #3639. 

This is a bit of an overhaul of the docs to make them more
easy to utilize. This changes include:
- Removal of overhanging public aspects of the documentation
- Reformatting of terminal commands to allow for easy copy & pasting
- Updating points of contact
- Screenshot Updates
- Automated code API documentation. [Google's docstring
style](https://github.com/google/styleguide/blob/gh-pages/pyguide.md#38-comments-and-docstrings)
should be used.
- Added variables for things like software versions & packages.
- Unless python & node version are manually specified, when docs are
built these will be pulled from
[`.nvmrc`](https://github.com/HyphaApp/hypha/blob/main/.nvmrc) &
[`.python-version`](https://github.com/HyphaApp/hypha/blob/main/.python-version)
- Consolidated the production and development guides into one location
(both under `Setup` rather than one under `Getting Started` and one
under `Setup`), and updated them to be similar to one another.
- Added different steps for getting Hypha development deployed under
multiple OSs

Add personality and make things a bit clear. 

Fixes #3074

The React app or "three column view" was built for an organisation that no longer use Hypha. No current implementors use it. Removing it simplifies Hypha quite a bit.
