[V2] Make use of `NSAttributedString.TextHighlightStyle` with next version of macOS

[weisJ]

The next version of macOS adds text highlighting capabilities similar to how search results are displayed in Safari, Notes etc. Maybe this could be added as an option for the search result highlighting in Maccy also.

I think it should be possible to implement it even on Sonoma by using NSColor.findHighlightColor. The only caveat is that the selected item color is white which makes unreadable on the yellow background. Here is a quick example:
