'Ctlr-click' text hint in Element picker mode should be 'Cmd-click' for macOS

[z0rc]

Describe the issue

Right now hint next to 'Cosmetic filters' says Click, Ctlr-click, this is true for Windows and Linux, but on macOS Ctlr-click doesn't work as expected, if brings up a Firefox context menu. You actually have to use Cmd-click to archive the same result as Ctrl-click on Linux.

Already fixed.

Fixed for Safari, but not for other browsers on MacOS.

Essentially duplicate of #614.

[uBlock-user]

That fix won't work if the uBlock-Safari repo inherits all of upstream repo's changes with every release, so the fix has to be made in the upstream repo itself.
