Add field / key autosuggestion for tag dog=

[RayBB]

Description

Hello,
I'm mapping some cafes in my area and many are explicit with yes/no for dogs.
Ultimately, I'd like to make a little interactive tool for my area to show dog friendly cafes (kinda like https://mapcomplete.org/pets.html?z=16.5&lat=4.731443461978699&lon=-74.04162554409845#node/703563897)
It would be nice if dog was part of the fields autocomplete so I don't have to manually enter the key each time.

Thanks!
