Update ci.yaml (#1063)

Increase the batch count to unbreak CI. CI appears to be running out of
disk space during linking.

<!--

IMPORTANT:

> Making changes to examples? 

Be sure to make example changes in the awsdocs/aws-doc-sdk-examples
repository (https://github.com/awsdocs/aws-doc-sdk-examples).
The examples in aws-sdk-rust are copied from the `rust_dev_preview/`
directory in that repository.


> Making changes to code?

All the code in aws-sdk-rust is auto-generated by smithy-rs
(https://github.com/awslabs/smithy-rs).
Changes to code need to be made in that repository.
