demote lint ImpliedQuantity to warning

This is hitting a lot of plurals, causing the CI builds to fail. But unfortunately, its getting it wrong. Its actually for a format in a string like "Updated today" in languages like pt that need special cases for 0/1 items. In this case, it makes no sense to say "Updated 0 days ago".
