GitHub Dark Colorblind theme break point not visible for color blind person

[npalm]

I just have tried the color blind dark theme, which works great. Nice Job! One setting that does not work for me is the color of the breakpoint

I think using a light color for the breakpoint would be the best option for the contrast. Since the theme should address color blind people, I think it would be great to find a better default. What worked for me was overriding the theme in the settings file.

{
        "workbench.colorCustomizations": {
            "debugIcon.breakpointForeground": "#000000"
        }
}

This PR #299 might improve the breakpoint icon for the colorblind themes.
