Pull Request Overview
This PR addresses the issue with configuration source generation for dictionaries that have nullable enum values. The changes include adding a new test to verify this behavior, introducing supporting test classes and enums, and updating the code generation logic to unwrap nullable types correctly.
- Added new test case in ConfigurationBinderTests.cs to verify dictionary binding with nullable enum values
- Introduced OptionsWithDictionaryWithNullableEnumValue and MyValue enum in the test classes
- Modified CoreBindingHelpers.cs to unwrap NullableSpec for dictionary element types
