fix(developer): remove duplicate definition of function gs() in keyboards

[SabineSIL]

fixes issue #15503 :

Keyboards compiled to .js define the this.gs function twice in an identical way.

  this.gs=function(t,e) {
    return this.g_Main_0(t,e);
  };
  this.gs=function(t,e) {
    return this.g_Main_0(t,e);
  };
