Alias very_long_sleeves -> sleeves_past_fingers

BUR #49504 has been rejected.

create alias very_long_sleeves -> sleeves_past_fingers

I tried making a distinction between these tags in the wiki, where sleeves past fingers would be for just past the fingers and very long sleeves would be for well beyond the fingers, before realizing they're basically used for the same thing.

deprecate very_long_sleeves
mass update very_long_sleeves sleeves_past_fingers -> -very_long_sleeves

I realized this needs some gardening first to clean up cases where people misused it for wide sleeves.
