ui_standards.rc: drop no longer used "options_choose_game_type" action
All consumers now switched to "options_game_difficulty"
No bump of version, as removing the unused entry should not effect anyone, both developers on master, and for endusers going from KXmlGui 5.* to KXmlGui 6.0 there have been already version bumps in the development cycle. So saving another version.
Depends on games/libkdegames!33 (merged)
