[#97] Introduce migration strategy for Terraform resource renaming

This commit introduces a strategic approach to renaming Terraform
resources within our AWS infrastructure, moving from the legacy codename
"VVA" to the new project identifier "GovTool". The migration is
orchestrated through the addition of two new Terraform files:
`vva_to_govtool_migration_20240212.tf` in both the main Terraform
directory and within the `govtool-ec2` module. These files serve as a
temporary mechanism to facilitate a seamless transition of resource and
module names across the infrastructure.

Key Highlights:
- The migration files outline a series of `moved` directives, explicitly
  mapping old resource and module identifiers to their new names. This
  approach ensures Terraform can manage the renaming process efficiently,
  minimizing the risk of resource duplication or loss.
- The migration is carefully planned to ensure no disruption to the
  ongoing operations, preserving the state of resources and their
  configurations throughout the process.
- A note within each migration file indicates their temporary nature,
  with instructions to remove these files once all stakeholders have
  successfully applied the migration. This step is crucial to prevent
  clutter in the Terraform codebase and maintain the integrity of the
  infrastructure as code practices. The migration files should be
  removed before project goes open source.

This renaming initiative is a critical component of our broader
rebranding efforts, reflecting the project's evolution and aligning our
infrastructure with the new brand identity.
