Chore: update `context.tf`, `build-harness` assets @korenyoni (#50)

what

• Update context.tf.
• Update build-harness assets by running make github/init.
• Clean up unused providers.
• Drop Terraform support prior to 0.13.

why

• The latest version of context.tf (null-label:0.25.0), contains new labels. A module instantiating this module with version 0.25.0 of null-label and making use of new labels will not be able to use this module.
• Running make github/init updates build-harness assets, which includes GitHub Actions Workflows and related files.
• The latest distribution of context.tf (null-label:0.25.0) is not compatible with Terraform 0.12.* because it makes use of validation blocks.
