fix: update terraform version

[Nico-dl05]

Motivation

Terraform version 1.10 was causing significant job failures during deployments. By reverting to 1.9.8, these failures are avoided, ensuring stable operations and reliable deployments.

---

Description

The Terraform version has been explicitly set to 1.9.8 in the deployment configuration.
This change directly addresses the issues caused by version 1.10, where a majority of jobs were failing unexpectedly.

---

Testing

This update resolves job failures without additional testing, as the change solely involves reverting to a stable Terraform version already used previously without issues.

---

Impact

• Performance: No performance impact.
• Configuration: Terraform version dependency pinned to 1.9.8.
• Documentation: No changes required.
• Dependencies: No new dependencies.
• Behavior: Fixes job failures by using a stable Terraform version.

---

Additional Information

Reviewers should note that this change only impacts deployments relying on Terraform. Teams using Terraform 1.10 should be made aware of potential job failures.
