Code Review

This pull request introduces the "Iceberg to AlloyDB (YAML)" batch pipeline template, including its Java metadata interface, YAML pipeline definition, configuration options, documentation, and integration tests. The review feedback identifies several critical issues: syntax errors in the YAML template's filesToCopy and requirements properties, the need to make the alloydbTable parameter mandatory rather than optional, the removal of the unused and unsupported query parameter across the interface and configurations, and a correction to the Terraform directory path in the README.

[gemini-code-assist]

The directory path is documented as v2/yaml/terraform/..., but the module is located under yaml/terraform/... in this repository. This should be corrected to avoid confusion when users try to navigate to the Terraform directory.

Suggested change

	cd v2/yaml/terraform/Iceberg_To_AlloyDB_Yaml
	cd yaml/terraform/Iceberg_To_AlloyDB_Yaml

this looks like it should be fixed in code to render correctly here. Let me open a separate PR to fix.
