Closes #158

Bumps aws-actions/configure-aws-credentials from @v3 (Node 16) to @v6 (Node 24) in terraform-plan.yaml and terraform-apply.yaml. Nothing else changes; the inputs in use (role-to-assume, role-session-name, aws-region) are unchanged across v3→v6.

Before merging

• Terraform plan (OIDC) ran on this PR and the configure-aws-credentials step succeeded
• Posted plan shows no resource changes

Heads up: merging triggers Terraform apply (OIDC) against the production account (workflow files match the **/*.yaml path filter).

After merge

• Confirm the apply run succeeded with no changes
• Comment on Bump aws-actions/configure-aws-credentials from v3 to v6 in incubator's Terraform workflows #158 with links to the plan and apply runs
