The phishing warning page URL environment variable has been renamed
from `PHISHING_PAGE_URL` to `PHISHING_WARNING_PAGE_URL`. We call this
page the "phishing warning page" everywhere else, and this name seemed
better suited (it's not a phishing page itself).
The variable has been listed and documented in `.metamaskrc.dist` as
well.
