NetBird 0.82 drops MySQL: how to migrate to PostgreSQL before upgrading with Docker

NetBird 0.82 removed the MySQL engine, and the server stops with the error the MySQL store engine is no longer supported. Roll back to the 0.81.5 image, move the data to PostgreSQL with the netbird-mysql-migrate tool from that same version, because 0.82 no longer ships it, and only then upgrade by pinning the 0.82.0 tag.
