Love Live! group tag utility aliases

BUR #56516 has been approved by @nonamethanks.

create alias liella!_1st_generation -> liella!_first_generation
create alias liella!_2nd_generation -> liella!_second_generation

I mainly chose to name the tags the way they are for consistency with liella! first generation lovelive! ~wonderful starlines~, but most tags use the cardinals, like 1st generation (hololive) and six other tags, compared to... iphone (first generation) (lol). Same goes for 2nd/second. I am aware the first gen tag will overtake the hololive one if this goes through lol

create alias hasu_no_sora_102nd_class -> hasu_no_daisankaku
create alias hasu_no_sora_103rd_class -> hasu_no_sanrenka
create alias hasu_no_sora_104th_class_(104th_year) -> hasu_no_shousankaku
create alias hasu_no_sora_104th_class_(105th_year) -> hasu_no_shoushihenkei

This may or may not help some find these group tags, as they may not know their exact names because they're romanized. Also, I just made hasu no sora 106th class (Kinjo Maika, Reisawa Aoi, Shinowa Mion) for lack of any name. They'll probably get a proper name later. The 105th class is just Ceras Yanagida Lilienfeld and no one else.

Why are there two tags for the 104th class? Because Katsuragi Izumi. She transferred late.
