rename o-i_superheavy_tank_series -> o-i_(tank)
I initially created the tag "O-I superheavy tank series" as a catchall tag for the supposed variant of the Japanese O-I tanks. But after it turned out that the "variants" prominently depicted in World of Tanks are actually just a speculative sketch, and that the "150 tons" variant is the only real variant, I felt like this tag's current name would be quite misleading, so I suppose that it should be renamed accordingly.
Though, I'm a bit wondering on what to do with the now confirmed fake variants of the O-I, such as the "O-Ni" and "O-Ho", as they are drastically different from the O-I. Should they get a separate tags?
