Read annotations on MediaEntity paths that are structural paths

[andrueastman]

Taking a look at the reference document at https://learn.microsoft.com/en-us/graph/api/driveitem-get-content-format?view=graph-rest-1.0&tabs=http

The /content path supports taking a queryparameter of the name format. As this is a structural property that returns a stream type, it is resolved to the MediaEntityOperationalHandler

https://github.com/microsoft/OpenAPI.NET.OData/blob/master/src/Microsoft.OpenApi.OData.Reader/Operation/MediaEntityOperationalHandler.cs

Due to the path being a structural type, the annotations are not read during the conversion process as annotations are read if the path is a NavigationPropertyPath and not if its a structural path. (Only the description is read)

OpenAPI.NET.OData/src/Microsoft.OpenApi.OData.Reader/Operation/MediaEntityOperationalHandler.cs

Line 47 in 2c1883e

if (IsNavigationPropertyPath)

Due to this, adding annotations makes is not possible to add query parameters to this path.
