Dev Notes: Add section on E2E tests

Let's add instructions on running the E2E tests

@anubh-v Not sure if this is too in-depth or is missing any crucial info. Is the structure of it okay as well?

Dev notes are very helpful 👍
I think I picked up a few spelling errors, and having a newline above headings would make it more readable without preview :)
Other than thanks for the hard work!

Sure! Haha I think the syntax highlighting lit up the headers for me so I didn't think about adding spaces. I'll put them in for clarity 👍

Thanks for working on this. It looks good overall, but let's reorder the sections and use more descriptive section headings.
