Alias the "hiroshima_and_nagasaki" tag

BUR #11390 has been approved by @nonamethanks.

create alias hiroshima_and_nagasaki -> atomic_bombings_of_hiroshima_and_nagasaki

The tag currently used specifically for a post related to the Hiroshima and Nagasaki atomic bombings are called "hiroshima_and_nagasaki", which is too vague, as most people will search "atomic bombings" before the city name itself. So I think it should be renamed to reflect what the tag actually means.

Edit: Well, I think the first proposal is quite unpopular and I understand that. I'll separate this suggestion with the other one.

I think what you're looking for is an alias, not an implication or rename.

I'm in favor of aliasing atomic bomb and nuclear bomb to nuclear weapon.
