¿Por qué mi discourse sigue en la rama /master después de reconstruir git con pruebas pasadas?

Why my discourse is still in/master branch after rebuilding test-passed git

This page shows the test-passed tips.

Now my discourse version is 2.9 beta 4

I put the version: test-passed in the /containers/app.yml, and I git pull, then rebuild, and after this, the build is still 2.9 beta4
