Exclude member display name changes form default push rules

### Your use case

In EW we currently do a workaround to not mark rooms as notified if they have a member display name change.
The push action from such an even is however sending a type `Notify`!
This means that other clients that do not include this custom behaviour to silence this particular `Notify` push action will end up marking rooms as unread.

The easy fix is: turn of: `New room activity, upgrades and status messages occur` in EW.

But I would like to be notified about room name changes just not about display name changes.

So I propose to change the configuration that is set when activating `New room activity, upgrades and status messages occur` to not include display name changes.
