[#97] Rename application components in infrastructure configuration

This commit encompasses a series of updates to the infrastructure configuration
of the GovTool project, aligning with the rebranding initiative detailed
in ticket #111. The modifications include renaming Terraform modules,
EC2 instances, and related infrastructure components from 'vva' to 'govtool'.

Technical Details:
- Updated the DEPLOY.md documentation to reference the new `govtool-ec2` module
  instead of the old `vva-ec2`.
- Renamed Terraform modules in `main.tf`. For instance, `vva-ecr-be` is now
  `govtool-ecr-backend`, and `vva-ecr-fe` is `govtool-ecr-frontend`.
- Updated various Terraform configurations, including resource names and module
  references, to reflect the new `govtool` naming.
- Renamed files and modules within the `infra/terraform/modules` directory,
  such as changing `vva-ec2` to `govtool-ec2` and updating associated files like
  `user_data.sh` and `variables.tf`.
- Adjusted the Makefile in the `scripts/govtool` directory to check for
  the renamed Terraform module `govtool-$(env)-$(cardano_network)`.
