fix: Added terraform install to pre-commit.yml

[AncientPatata]

Motivation

Pre-commit job is unable to find Terraform, I think we're relying on one of the steps to install it for us when we should be installing it ourselves to have more control over it.

Description

Added a step to install Terraform.

Testing

None.

Impact

To be determined;

Additional Information

None
