[Bug]: IgnoringType is ignored if type is in a ValueType

[davidmehren]

Description

When a type is stored inside a ValueType, like a tuple, it is not ignored when checking structural equivalency (IsEquivalentTo), when it has explicitly been excluded via IgnoringType.

This has been caused by #4263

Expected Behavior

Types that are specified in IgnoringType are ignored, even when they are stored in a ValueType.

Actual Behavior

Equivalency for these types is checked and tests unexpectedly fail.

Steps to Reproduce

See my reproducer at https://github.com/davidmehren/TUnitIgnoreTypeRepro/blob/main/Tests.cs

I would expect both tests to succeed.

IDE-Specific Issue?

• I've confirmed this issue occurs when running via dotnet test or dotnet run, not just in my IDE
