Consider updating Azure.Storage.Blobs to latest once linked issue is resolved

See Azure/azure-sdk-for-net#41894

OR, if they decline to address the issue just change call to:

 client.UploadPages(new MemoryStream(new byte[BlobSize]), offset: 0, conditions: new PageBlobRequestConditions(){LeaseId = handle.LeaseId }, progressHandler: null, transactionalContentHash: null, cancellationToken: default);
