👷(project) streamline Docker image publishing workflow

Refactored 'Hub' CI job for clarity, using 'docker/build-push-action.'
This dedicated workflow efficiently manages image releases on push tag
and main branch merges events.

'Hub' job was broken by Chat GPT translation from Circle CI.

Images are pushed to a temporary Docker Hub repository,
lasuite/people.

Duplicated 'build-docker' job was removed from people workflow.
