Continued update to the "add your profile" README instructions

[TimJohns]

I updated the three remaining screenshots I wasn't able to get into the earlier PR similar to this one, added one bit of clarifying text, changed one path I missed earlier, and (unfortunately for the diff...) indented the text in the git bash instructions so that the numbering would continue afterward.

I also changed my latitude by one digit for the purpose of capturing the screenshots - I probably could have unstaged that before switching branches, but it seems harmless -- and I'm not sure how to unstage it now that I've pushed another commit after it, so please ignore.
