Adds page limit validation for dispute evidence
Stripe now validates the estimated compiled page count of evidence submitted when you update a Dispute. If the estimated page count of your text fields and file uploads exceeds the network page limit, the API returns a 400 error with the code dispute_evidence_page_limit_exceeded. This validation applies whether or not you set submit to true, so you can catch oversized evidence before final submission. Previously, you could update a Dispute with evidence of any length. Now, if the evidence exceeds the compiled page limit, the requset fails and returns a 400 invalid_request_error with the code dispute_evidence_page_limit_exceeded.
