Cannot Generate Open API swagger.json file if inheriting from ITableEntity From Azure.Data.Tables

**Describe the issue**

We recently have run into an issue where after upgrading our Azure Storage SDK to support managed identity we can no longer generate the swagger.json file. The error we receive is:

Method 'get_ETag' in type '' from assembly ', Version=X, Culture=neutral, PublicKeyToken=null' does not have an implementation.

at Microsoft.Azure.WebJobs.Extensions.OpenApi.OpenApiTriggerFunctions.RenderSwaggerDocument(OpenApiHttpTriggerContext openApiContext, HttpRequest req, String extension, ExecutionContext ctx, ILogger log)

**To Reproduce**

1. Create an Http Trigger
2. Ensure you are running Azure.Data.Tables version 12.8.1
3. Have the Request Body Type include a class that inherits from ITableEntity
4. Attempt to Generate swagger.json file by visiting URL upon building

**Expected behavior**

We can generate the swagger.json file when using native Microsoft Libraries.

**Additional context**

I did some initial investigation and this seems related to feature request #327 where we either need to added the allowance of custom visitors or include E_Tag in the core code. For now I've created Tags that exclude the affected endpoints so I can compile the Open API spec. Any additional help would be greatly appreciated.

Reproduce with Azure.Data.Tables 12.8.1 using an Http Trigger whose request body includes a class implementing ITableEntity, then generate swagger.json. Start at DocumentHelper.GetOpenApiResponses and follow the calls through Document.Build and RenderSwaggerDocument. Done means the swagger document generates without the get_ETag reflection error while preserving the affected endpoint schemas.
