Add a possibility to get webUrl to student submission page for teacher.

Hello!

I asked this question on https://stackoverflow.com/questions/71797043/ms-graph-api-how-to-get-weburl-to-student-submission-page-for-teacher and on https://docs.microsoft.com/en-us/answers/questions/808309/ms-graph-api-how-to-get-weburl-to-student-submissi.html. On https://github.com/microsoftgraph/microsoft-graph-docs/issues/16483 you don't allow ask such questions.

So it would be very helpful if the 'webUrl' property appeared in https://docs.microsoft.com/en-us/graph/api/resources/educationsubmission?view=graph-rest-1.0#properties of properties for educationSubmission.

Thank you!
