[ApiView] Change in operationId should not look like entire operation was deleted and added

In the APIView for [PR 21240](https://github.com/Azure/azure-rest-api-specs/pull/21240), in the diff from revision 0 to revision 1

https://apiview.dev/Assemblies/Review/403f16af88e945baba69c06c0c445bea?diffRevisionId=06f379cd9bfe4f479a50d6efd1c14837&diffOnly=False&revisionId=dee606fa43c04080b8a89bb7cf31fa7b&doc=False

The GET on /linkconnections, and PUT, GET, and DELETE on /linkconnections/{linkConnectionName} _look like_ the entire operation is deleted and then re-added.

But in fact the only changes that happened in these operations was that the operationId changed.

< "operationId": "LinkConnection_DeleteLinkConnection",

> "operationId": "LinkConnection_Delete",
```

It would be really nice if APIView would show that only the operationId was changed in these situations.

Start by reproducing the linked APIView diff for PR 21240, comparing revisions 0 and 1. Trace how APIView matches operations when only operationId changes; done when those examples show an operationId field change rather than a deletion followed by an addition. The issue names no source files or tests.
