Roff good first issues

This issue addresses limitations with GitHub Actions cache for build matrices, specifically the 10GB limit and lack of intra-run sharing, leading to slower builds. Potential solutions include explicit scoping, using registry cache, or accepting the current limitations.

This issue proposes centralizing tool versions across the repository to prevent discrepancies between CI pipelines and validation scripts. The divergence is currently causing CI failures, specifically with Hadolint, due to different versions being declared in the action and the validation script.

This issue tracks the implementation of a Renovate custom manager to automatically update Terraform and AWS CLI versions in `supported_versions.json`. The process involves Renovate detecting version changes and a separate script materializing those changes, including GPG verification and test template synchronization.

Refactor the `gh-templates` project to remove the locally stored license files from the `templates` directory, relying instead on external APIs for license rendering. This involves updating the codebase to fetch licenses dynamically and potentially removing any related files and code paths.

The task is to remove the `install_issue_template.sh` script from the `gh-templates` repository because it's no longer needed. This involves deleting the script file and potentially updating any documentation or instructions that reference it.

Rename the GitHub Actions workflow file `update_changelog.yml` to `update-changelog.yml` within the `gh-templates` repository to adhere to a consistent naming convention. This involves a simple file rename and potentially updating any references to the old filename within the workflow itself.

Debug and fix a bug in the 'test issue template' of the `gh-templates` project. The issue manifests as a failure to function correctly within GitHub, as shown by an error message and screenshot. The solution likely involves inspecting the template's YAML or Markdown code for syntax errors or logical flaws.
