FIX: update normalize css from 3.0.1 to 8.0.1 (PR #10141)

It is a second attempt to this update. First one was reverted here https://github.com/discourse/discourse/pull/8618

We noticed a problem that like counter had incorrect colour on mobile.

I added a missing rule to the bottom of the file (that rule existed in normalize-3 and was removed in normalize-8)

button,
input,
optgroup,
select,
textarea {
  color: inherit;
}

I wonder if we should instead leave the normalize file as-is and put the backward compatible patch in another file?
