Update to use `terraform-aws-security-group` v2

[Nuru]

Describe the Feature

The Terraform resources around Security Groups have evolved, and this module is using the outdated v0.3.3 of terraform-aws-security-group. It should be upgraded to use terraform-aws-security-group v2.

Additional Context

The upgrade may be a breaking upgrade and need migration notes. See:

• terraform-aws-security-group v0.4.0 release notes
• terraform-aws-security-group v1 to v2 migration notes
