Accidentally swiping back on macOS

[gnapse]

As some others have stated in #5907, I find that Brave is too sensitive in detecting the gesture for swiping from right to left in the trackpad to go back in history. I don't want to disable the feature, as I relied on it when I used Chrome. But Brave is too sensitive. Sometimes I make the gesture to scroll up or down, and apparently in my movement in the trackpad, I also did move my fingers to the left slightly while doing the most significant up-or-down movement. Because it's happened to me several times that I go back in history with having had the intent to do so.

@gnapse I'm happy to report that with our latest release (0.20.30), this feature was finally delivered 😄

It was originally reported with #9615 and fixed with #9617

Please give it a go and let us know what you think! In addition to adjusting sensitivity, there is a visual indication when going back/forward on pages
