Better challenger: Ability to create "query template"

[SergioGlorias]

Often streamers who play with chat
They want the challenger to challenge them, they have some rules like:

• "can only be a maximum of 5+5"
• "only this game mode"

and to facilitate the challenge they use the link https://lichess.org/?user=SergioGlorias#friend

the idea was to improve queries so the streamer could generate a forced template
instead of using what is saved in your browser history

Note: the idea was that the challenger could edit it anyway
