Clarify the instance type to use for Aurora Serverless v2

[AP-Hunt]

Description

When creating an Aurora Serverless v2 cluster in Terraform, users must add an instance to the cluster. The documentation points to the AWS documentation page on the currently available instance classes, but this documentation does not include db.serverless.

The Aurora Serverless v2 documentation itself also has scant mention of it.

Including the information here as well ought to help users.

References

AWS documentation for the instance type

Output from Acceptance Testing

Docs change. Acceptance tests should be unaffected?
