NPC Dialogue Screen shows 2 close buttons

If you open a dialogue on the newest preview, you can see 2 close buttons in dialogue UI. Additionally the extra close button does not trigger commands on close.

*Steps to reproduce*

1. Open any dialogue UI as player in survival mode

*Where the bug is located*

The bug seems to be in `ui/ui_template_dialogs.json` file in vanilla resource pack. `common_close_button_holder` has a binding, that overrides `$show_close_button` with `(not #is_using_gamepad)`.

I confirmed, that by commeting out the binding, dialogue UI has again only one working close button.
