losipiuk / Github hide green checks

The GitHub CSS changed recently I guess and it broke the selector used to find the checks.

The following diff solves the issue:

$ diff /tmp/broken /tmp/fixed
60c60
<     var actionRuns = jQuery(".merge-status-item > .merge-status-icon > .color-text-success.octicon-check");
---
>     var actionRuns = jQuery(".merge-status-item > .merge-status-icon > .color-fg-success.octicon-check");
