Make "revert now" more obvious

[hrasyid]

Otherwise it's not obvious to people that they can revert.
Note: Only translated two languages, in other languages it will show up in English.

Ideally, a user click on the button "ShouldRevert", and it will let people mark it as "ShouldRevert" and then there is an additional button showing up, and asks "do you want to revert them directly?", if user continue to click on it, it will revert the revision. (and user shall be able to also decide that they can "always conduct revert when marking ShouldRevert" ).

Also, the revision needs to be eligible to revert - meaning:

• there is no other subsequent revisions after the current revision-in-review
• the revision and its proceeding revisions are not from the same user, see B: Handle consecutive vandalisms on the same Article. (Solution 1) #57

I would love to let this PR go through, even though I think it will only be a temp optimization. We need follow up commits for aforementioned functions.

There is one blocking request for you before I merge this PR in:

• can you make sure when people revert directly, their label also gets marked as "ShouldRevert"?

Nevermind, I found out that you are only adding a label, instead of showing the "should revert" all th time. This PR is good to go in.
