Add minecraft/profile/lookup/bulk/byname alias

As of 23w42a, the "Usernames to UUIDs" endpoint, previously at POST
https://api.mojang.com/profiles/minecraft, has been moved to POST
https://api.minecraftservices.com/minecraft/profile/lookup/bulk/byname.

This patch adds an alias for the new endpoint. The old endpoint will
still work.
