Removed the `docker-tag.yaml` workflow as it is no longer needed. Updated the destination tag format in `docker-master.yaml` and upgraded Node.js major version to 22 in the Dockerfile for compatibility and consistency.
Updated all instances of "GuillaumeHemmen" to "guillaumehemmen" in workflow files to ensure uniformity in repository URLs. This change prevents potential issues caused by case sensitivity in certain environments.
Replaced the Kaniko executor image with a self-hosted version to improve control and reliability. This ensures the workflow uses a specific version (`25.21.1`) hosted on `git.van-hemmen.com`.
Introduce four workflows to automate Docker builds and pushes using Kaniko. These workflows cover push events to the `master` branch, pull requests, tag pushes, and other branches. They streamline image publishing to the specified registry with proper secrets configuration.
