PIA-4102

• set individual background color for each individual help screen and its corresponding cells background within the both GiniConfiguration and GiniBankConfiguration
• cleanup Gini colors and added new colors that were used in multiple places

Unfortunately, for the Gini Bank SDK Example the new introduced configuration options will not work. To make it work we need to add them in

• public func captureConfiguration() -> GiniConfiguration and
• public func updateConfiguration(withCaptureConfiguration configuration: GiniConfiguration)

We need those additional steps because we modify the screens which are inside Capture SDK from Bank SDK. Check how onboardingCurrentPageIndicatorColor is used inside GiniBankConfiguration file 😇

Ohh, thanks for telling me. I've updated the pr accordingly.
