Image build (#3)

* Remove obsolete Lambda packaging script and related configuration files

- Deleted `package_lambda.py` script responsible for packaging AWS Lambda functions and layers.
- Removed `pip.conf` configuration file for pip settings.
- Eliminated `requirements.txt` file that specified Python dependencies.
- Deleted `test_payload.json` used for testing Lambda functions.
- Removed empty JSON and TFVAR files in `varfiles` directory.
- Deleted `variables.tf` file containing Terraform variable definitions.
- Removed `versions.tf` file specifying Terraform version requirements.
- Added new GitHub Actions workflow for building and pushing Lambda container images using Packer.
- Introduced `packer.pkr.hcl` file for Packer configuration to build Docker images for Lambda.

* Refactor GitHub API integration to remove Census-specific references and improve configuration handling

* Update Python setup in build workflow to use actions/setup-python@v4 and improve dependency installation

* Add Terraform backend configuration for GCS storage
