Change .desktop entry name from brave to Brave

Capitalize product name without changing name of the executable. All changes
apply to the the brave.desktop file which holds the name used in the application
menu and other points of desktop integration (app switchers, etc.).

(Please forgive me for fixing up the inconsistent whitespacing.)
