Request: add "play mode" to court

[homa8511]

As tournament organiser
I would like to add a "play mode" to each court
so that different forms of play are possible in a tournament.

Background:
In Germany and other European countries, children's football is currently being reformed. The children play tournaments instead of individual games.

The tournaments have several pitches with usually two alternating game modes, e.g. 3 vs. 3 and 3+TW.

If Bracket allowed the creation and assignment of game modes, it could be used to plan rounds of play in each-against-each.

Possible implementation:
A new table play_modes is created in which admins can add their own game modes.

Another table courts_play_modes maintains the connection between court and play_mode.

In the frontend, game modes can be created as free text. The assignment of play mode to court is made from a dropdown.
