Revert some changes to ListBox resources to have selected state be visible

Description

Revert some resource changes to make the selected item of the ListBox visible.

Few notes:

• Added cert and pfx file as otherwise test app won't compile anymore due to expired certificates
• This is not a hard reset of changes but rather an update of few brushes to get the desired behavior back while also keeping current XAML design

Motivation and Context

Closes #3808

I'm not sure if there are other colors that are going to have incorrect contrast ratio. If fixing just these makes everything meet contrast ratio, then we should be good. I'll let @YuliKl make the call.

@YuliKl Lets take this fix. If there are more bugs that come up, we can re-evaluate a rollback.
