Change pronoun `I` to `we`

• It changes pronoun I to we, throughout the book.
• It also updates url to 2nd edition of R4DS, rather than the 1st edition.

Thanks so much for this. I think I'll ping both @hadley and @thomasp85 on this one: do we want to change to a collective authorial voice? Seems to me that the arguments in favour are:

• grammatically consistent with the fact that there are now three authors on the book
• also consistent with the shift to ggplot2 as a community project with broader governance

I could also make the argument against by noting that the first two editions has a strong "Hadley-style" authorial voice that we've mostly preserved, and shifting to the collective does slightly shift the feel of the text?

My personal opinion: I hadn't been particularly worried about the pronoun (heck I have a solo author book that still refers to me as "he" throughout), but now that Zeki has kindly opened this PR as the starting point, it seems like a good idea.

Yeah, I think it's better to switch we 😄
