Better Example URLs for dynamic suffix {catch_all} and multiple suffixes + patterns

[DiegoPino]

What?

The logic that builds the example URLs is limited. It needs to

• Show URL variations for every static suffix (if any)
• If Variable {catch_all} suffix is used an example should also be provided
• When static extra prefix/suffixes are used for the Variable (the value to be matched against the Search API field value) then those values need to be removed from the random/example value we get from the Search API for the example URL
