Fix the ${hash} substitution for diff file web links

It seems that when we were refactoring this change to address review
comments we accidentally swapped out the ${hash} replacement for a
revision replacement. Fix this by swapping it back to a hash replacement
which was the intended behavior.

Note we skip release notes as this addresses a bug in a recent change
that should have accurate release notes already.

Release-Notes: skip
