Pull Request Overview
This PR prevents Basic authentication from mistakenly using DefaultCredentials in SocketsHttpHandler.
- Adds a conditional check in the Basic authentication case to skip processing when DefaultCredentials is used.
- Enhances the authentication handling by ensuring only supported credential types are processed in Basic auth.

- [nitpick] Consider verifying that the variable name 'credentials' is consistent with other parts of the code where a similar credential is referred to as 'credential'. If applicable, renaming it for consistency may help reduce confusion.
if (CredentialCache.DefaultCredentials == credentials)

Updated the SocketsHttpHandler_UseDefaultCredentials test to utilize [Theory] and [InlineData] attributes, allowing for testing with both Basic and Digest authentication types.
