Detach code block background color from OverlayDark

[kelltom]

Just wanted to drop a quick issue here in case anyone is maintaining.

I notice that it's not really ideal to have the code block's bg color tied to OverlayDark. The below examples are using the default MudBlazor theme colors.

In light mode, you'd end up with something like this, which has poor contrast:

Although it looks quite good in dark mode:

We can lighten the OverlayDark in the MudBlazor Theme config, but this changes the appearance of all of our dialog backgrounds to appear washed out, as opposed to making a shadowy appearance.

Is there some better way to isolate the color of the code bg in light mode?

https://mudblazor.com/customization/default-theme#palette provides all available colours and back in the day OverlayDark seemed like the best option (even though it was not great in the light theme). Maybe there is something better now, but trying all options will take some time. Maybe OverlayLight would be better, but rgba(255,255,255,0.4980392156862745) seems like super white

I found a pretty decent compromise in setting:

OverlayDark = new MudColor(100, 100, 100, 0.3).ToString(),

This way, there's still a noticable tint when pulling up MudDialogs, and markdown looks good.

I think that --mud-palette-chip-default is a pretty good option from the default library:

Light

Dark
