Improve Meltano contributing guide for UI
https://meltano.com/docs/contributor-guide.html#setting-up-your-environment
These instructions do not include setting up a virtual environment. There's a reference to meltano-development
which I don't see on that page.
Having a full and clear set of instructions for how to review changes from a specific git branch would be great.
@alex1126 did you have the same setup experience or am I missing something?
