Tag alias: pointy_shoes -> pointy_footwear

BUR #3107 has been approved by @NWF_Renim.

create alias pointy_shoes -> pointy_footwear
remove implication pointy_shoes -> shoes

Provides consistency with the other x_footwear tags; shoes are not the only footwear that can be pointy.

+1 I've been very much wanting this one for a while, but never got around to making the request.

Approved the alias, though with the broadening of the tag I feel that we may want to consider removing the aliases of curled_toe_shoes and curled-toe_shoes as I could foresee us potentially needing a curled-toe footwear tag as a subtag of pointy_footwear in the future.
