Use PartitonKey In update/Delete queries

[aspladypfl]

Currently, Updates/deletes only work if the partionkey and the id are the same value. This change will now respect the requestOptions.partitionKey optional value

Hey this looks good.. a few suggestions that would speed up merging:

• Add new test cases that validate a full CRUD cycle

You can copy the existing integration test file and add partition keys for those operations. It would be great if they also covered correct handling of a non-happy scenario (for example, excluding a required value or passing an invalid value). These test run locally using the Vercel local CosmosDb-Server so you should easily be able to run them using npm test.

• Remove the changes on package.json and package-lock.json

I don't think you changed anything in these so this keeps the PR cleaner and less worry that anything broke by mistake.. I'll update those in a separate PR (you can probably see I'm a bit behind on catching up on dependancies.. I need to get to that soon)

With these two things, I think we'd be in good shape to merge. Thanks for taking the time to submit this!

Alright I have updated the PR to add more testing infrastructure and PR comments
