[PROPOSAL] Update the contributing docs to include minimum tooling requirements.

[tannergooding]

Rationale

Developers looking to contribute may not always use the command line or stay up to date with the latest tooling/previews and so they may run into accidental issues when the repo moves forward.
As such, it would be beneficial if the contributing docs and potentially the readme clearly called out the tooling requirements for the repository.
This includes both the command line and graphical experience via an IDE like Visual Studio.

Alternatives

Some of this could be simplified by enabling experimental work as opt-in or by doing it in a separate branch. However, developers would still want to know those dependencies and so something like the above may still be required.
