Describe the bug

Related to microsoftgraph/msgraph-beta-sdk-go#410 and microsoft/kiota-dotnet#277

At the moment, enum parsing functions are generated with the default case returning an error. This causes failure of parsing the entire payload in such scenarios where the API is updated. To be more lenient and align with other languages, the parsing methods should return nil rather than throwing an error.

Expected behavior

Return nil for the default case.

we could make the change on the parsing side without causing a breaking change since:
the parsing methods already return a pointer
the parse node interface returns any, which can be nil

How to reproduce

Make a request to a an api that returns an undocumented enum member, error is thrown preventing the parsing of the entire payload.
