OPCT-257: CI fix release/publish pipeline on GHA (#114)

This PR review the Github Actions (GHA) pipeline when
publishing/releasing a new image when push to tags and `main` branch.

Additionally, it merges the linters and e2e to a dedicated workflow
definition file.

It will also use the same workflow file to the entire pipeline,
preventing managing many configurations for different events.
