[.NET APIView] .NET Parser incorrectly generates duplicate line ID

For the .NET ApiView Parser, this issue is occurring consistently. The main implication is that it causes failures when running Generate copilot review, and ApiView does not accept submissions with duplicate line IDs.

We plan to enforce a policy to prevent this, and an active effort is underway: https://github.com/Azure/azure-sdk-tools/issues/11591.

This can be observed in: [System.ClientModel](https://spa.apiviewstagingtest.com/review/1b123e7a51d44ebe945f0212ee039c65?activeApiRevisionId=979b77a978bf4633a2c46a72547a9f12) with the line ids: ` System.ClientModel.Primitives.PipelineRequestHeaders.GetEnumerator()`

This is a longer list of duplicate line ids examples:
