Overview: Export of "Package" record with number of "Titles" between 9900 and 10000 is failing with error.
Steps to Reproduce:

1. Log into Snapshot FOLIO environment as User with the following permissions:
   Export manager: All
   eHoldings: Can view providers, packages, titles detail records

   Agreements: Search & view agreements

2. Go to the "Package" records: "/eholdings/packages/125531-2631932".

3. Apply the filter to "Titles" by name "Africa".
   Actual result: Records found = 9923 under "Titles" accordion.

4. Click on the "Actions">>"Export package (CSV)">>"Export".

5. Go to "Export manager" app and wait for the export to be complete.

Actual Results: The export job failed with error: "Expected results set exceeds maximum of 10000; please decrease size/offset values to request results set less than maximum.\"
Additional Information:
1) The export job fails with that error only when the number of "Titles" in exported "Package" records is between 9900 and 10000.
2) Full text of the error message:

Possible solution: Decrement count when page*count = 10_000 to have page*count = 9_999
