Feature Request - Remove "DGT Board" Play menu shortcut

[tors42]

It would be nice if it was possible to remove the "DGT Board" Play menu entry.

The "DGT Board" Play menu entry is added when one configures a DGT Board at https://lichess.org/dgt
, but there is no way to remove the shortcut after it has been added.

(One example implementation of how one could make it configurable exists in #15044 , but that solution would probably be better off by populating the form based on the server side value, rather than trying to keep local-storage in sync. And maybe there are simpler solutions one could come up with.)
