What's Changed

• Modernize Docker configuration, now using Debian bullseye and Python 3.11.
• Improve nightly and on-PR Docker builds.
• Add versioning based on Git tags, using versioningit. This will aid in telling PR- and nightly releases apart from GA releases when running mqttwarn --version.
• Improve Apprise integration by propagating the mqttwarn data dictionary into the Apprise plugin template arguments. Thanks, @zoic21.
