Added scope for Find In Files: File Name

File names in the Find In Files view are not currently highlighted, making the results difficult to read. I created a scope for these filenames, using cyan (#2AA198) for both light and dark. After testing the entire palette,I found this to be the most aesthetically pleasing choice.
