Specifying None as serializer/deserializer breaks kiota update

[ajtribick]

What are you generating using Kiota, clients or plugins?

API Client/SDK

In what context or format are you using Kiota?

Nuget tool

Client library/SDK language

Csharp

Describe the bug

After generating a C# client passing the options --deserializer=None --serializer=None a client is generated without any default serializers. If the OpenAPI spec is then updated, running kiota update fails with "sequence does not contain any elements"

Expected behavior

The client should be updated

How to reproduce

• Create a C# client with no default serializer/deserializer factory
• Modify the YAML spec
• Run kiota update

Other information

Based on a quick debug, it appears that the kiota update command is trying to set up a factory class called "None", rather than treating this as an indication that there should be no default factories.

further update - looks like it works if you use "none" rather than "None". Looks like a case (in)sensitivity mismatch between kiota generate and kiota update.

Thanks for raising this @ajtribick

Looks like the hashset with the configurations are not set with the same comparers when the lock file is read. Authored #4923 to resolve this one.
