Refactor deployment and secret configurations

Simplify the Makefile and update the deployment.yaml and secret.yaml
files. The Makefile now uses a simplified registry variable. In the
deployment.yaml file, the image repository, tag, operating system, and
architecture have been updated. The secret.yaml file now uses the
'tokenKey' key instead of the 'secret.key' key.

These changes improve the clarity and organization of the codebase and
ensure accurate deployment of the application. They also align the code
with the updated image repository and tag. No breaking changes or issues
are expected.
