I suggest adding a key "teams.name " at the endpoint "Get team standing of a team battle" https://lichess.org/api#tag/Arena-tournaments/operation/teamsByTournament. Perhaps it will be useful at other endpoints as well. This will be very useful for teams whose name is not written in English and therefore differs from their ID. Now, to get the name of each team in team Arena, you have to make a separate request, which increases the load on the server.
