Background and motivation

When referencing the FluentAssertions nuget package a five years old version of the System.Configuration.ConfigurationManager package gets referenced transitively. Those ancient 4.x.x versions of "System" nuget packages will eventually get marked as deprecated. Consider upgrading the ConfigurationManager version to something in support, i.e. 6.0.1.

This only impacts the net6.0 as it's the only TFM that references the package.
