Increase the color contrast for Gin switches

I'm working on this

I changed colors in dark mode, so the Gin switch component meets SC1.4.11.
Can you follow up with how to test Forced colors issue as I'm new and didn't find a way to turn it on and replicate the issue.

Go to Developer Tools on your browser, then ctrl+shift+P, then type force and click on the Emulate CSS forced-colors: active.
By this way you can active the forced colour mode on your browser.

Thanks, I added a fix for ensuring that the toggle in the unchecked state is visible in Forced Colors mode

Hi @tomislav.matokovic ,The merge request MR!583 has been tested and verified. After applying the MR, I can see an increased color contrast in the toggle. Adding screenshots for reference.

Does this need another review? I didn't see the comments from @rinku jacob 13 visible.

It looks like @tomislav.matokovic has a patch and have before/after images.

I can see that there does seem to be better support for darkmode, but I don't understand this CSS enough to evaluate the code.
