BUR #18977 has been approved by @nonamethanks.
rename merkava -> merkava_(tank)
rename merkava_(personification) -> merkava_(tank)_(personification)
The tag for the Israeli Merkava tanks currently has no qualifier, despite there are character from Under Night In-Birth with the same name. So I think it needed one to futureproofing and avoid confusion.
Also added the qualifier to the currently one-off personified Merkava tank tag, with the same reason explained above.
