There are multiple issues with that line:
* Other languages might have the application name before their version of 'About'. The previous line can't account for those languages because the application name is always appended at the end.
* The old one was trying to translate CuraApplication.applicationDisplayName which can't be statically determined.
* The old one had no explanation towards the translator.
Most stuff here was recently changed. Some of it was where I found a pattern in something that was likely copy-pasted from somewhere else, so I did a global search and replace on that.
Contributes to issue CURA-5784.
