Avoid extra indentation on Go switches (#6817)
Unlike other languages, in Go, switches themselves are not indented;
it's just each case body which is indented by one level:

   switch foo {
   case "bar":
      baz()
   }

As such, we shouldn't `@indent` for type_switch_statement nor
expression_switch_statement, as otherwise inserted lines show up as:

   switch foo {
      // inserted with "o"
   case "bar":
         // inserted with "o"
      baz()
   }

With the fix, the inserted lines are indented properly:

   switch foo {
   // inserted with "o"
   case "bar":
      // inserted with "o"
      baz()
   }

I also verified that indentation on selects similarly works well.

Thanks to Triton171 for helping with this fix.
