Alias standing 69 to upright 69

BUR #41513 has been approved by @nonamethanks.

create alias standing_69 -> upright_69

I created and populated standing_69 without realising that upright_69 already existed.
However, I'm bit torn on which one should be aliased. One one hand, upright_69 is similar to upright_straddle, but standing_69 is similar to standing_sex, and is also the first name that came to my mind for this act.

create alias upright_69 -> standing_69

The alternative to the above.

there's many posts that are upright but not standing, like post #103455.
