Pull Request Overview

This PR extends Dependabot configuration for Terraform to scan all subdirectories instead of only the root directory. This enables automatic dependency updates for Terraform modules located in any subdirectory of the repository.

• Changed from single root directory scanning to recursive subdirectory scanning for Terraform dependencies
• Uses glob pattern **/* to include all nested directories

[Copilot]

The configuration uses 'directories' field, but the correct field name for Dependabot is 'directory' (singular). Dependabot does not support multiple directories in a single configuration block. To scan subdirectories, you should either use 'directory: "/"' to scan recursively from root, or create separate configuration blocks for each specific directory.

Suggested change

	- "**/*"
	directory: "/"
