Unmisplace edit button in Diffusion
Summary:
It is misplaced from the beginning but it got worse after some CSS tweaks.
I was also thinking about using the same DropdownMenu as in Differential but I don't feel strongly about it to do it myself.
Test Plan:
Display file in Diffusion.
Repeat with disabled Editor.
