Updated Docs with correct amounts for Batch Requests

[TomBillingtonUK]

The Microsoft Docs say the limit is 1000, not 100.

We have also done some local testing and the code can deal will 1000 requests as soon as we hit 1001, Microsoft returns with "The current change set contains too many operations. A maximum number of '1000' operations are allowed in a change set"
