DEV: Remove text-overflow component and use CSS line-clamp instead (PR #10196)

We used this in 3 places and they’re all capable of using CSS line-clamp (which works without requiring a page refresh, more details on Meta), so I’m removing the component.

I also had to replace single quotes in user-card-contents.hbs to pass the ember template lint.

I’m always happy to remove stuff like this. However I sent you a PM because I believe one of our private themes is affected by this and needs to be addressed when you merge it.

ok, there were 3 private customer themes and 1 plugin, and those have all been updated to remove {{text-ellipsis}}
