* refactor: cra build path
The `authelia-scripts` helper currently performs steps to move files around in different stages of development and CI/CD.
We now utilise the `BUILD_PATH` environment variable to adjust the output directory for the web frontend from the default of `./web/build/` simplifying the helper somewhat.
Additionally we no longer build the Go binary in the unit test stage of our CI/CD as this is not necessary.
* fix: build output directory in coverage dockerfile
