#### Summary <!-- Provide a general summary of your changes -->

This updates port validation error text assertions in
UriBuilderTest.Codeunit.al to align with updated underlying exception
message changed in .NET 8. The old validation texts remain to keep
compatibility with platform versions based on .NET 6.
