[kcmkwin/touchscreen+screenedges] Call KRunner KRunner
In the context of the Touch Screen and Screen Edges KCM, using the term "Run Command" to
refer to KWin is inaccurate and misleading. By using a string that starts with an action
verb and no ellipses, it is suggested that the action is literally to run some command,
prompting the user to think "which command will it run? How do I choose what it is?"
This patch changes the action text to "Show KRunner" which is the proposed new standard.
See T10966: Unify how we refer to KRunner for more information and reasons why to do this.
