Problem:
In Vector skin, the "Edit links" button of Languages section of right menu do not pass WCAG's AA level (#72777d on #f6f6f6 has contrast ratio 4.17 according to https://contrast-ratio.com/#%23f6f6f6-on-%2372777d or 4.18 according to Mozilla Firefox's dev tools; recommended value is 4.5).
We want to change it to #54595d to increase contrast.
