fix macos builds (invalid export format)

- remove gh workflows as they were never executed in this fork
- removes "SubDirectoryLocation"
- expects your `export_path` to be `./build/...`
- remove test projects
- use `lf` eol
- remove contributors as this file wasn't up-to-date since forever
- remove some `Dockerfile` labels
