Hover state needed for copy icon on commit page
There is currently no hover state for the copy icon on a commit page. This is inconsistent with our copy icons elsewhere.
Example page: https://gitlab.com/gitlab-org/gitlab-ce/commit/e2f0b83061df3b19b683b67d142acea65d5df0fd
Current
The current color on hover is: rgba(0, 0, 0, 0.55);
Proposal
The color on hover should be: rgba(0, 0, 0, 0.85);
