Fix path to introduction notebook

Binder build of this repository fails with the following output:

Waiting for build to start...
Picked Git content provider.
Cloning into '/tmp/repo2dockerjuuhwwu_'...
HEAD is now at 9936fc2 Merge pull request #26 from gesiscss/ctr26

COPY failed: file not found in build context or excluded by .dockerignore: stat intro_to_persistent_binderhub.ipynb: file does not exist

I fixed the error by changing

COPY intro_to_persistent_binderhub.ipynb ${HOME}/intro_to_persistent_binderhub.ipynb

to

COPY .binder/intro_to_persistent_binderhub.ipynb ${HOME}/intro_to_persistent_binderhub.ipynb

Fixes #29

@MridulS can we merge this?

Thanks for the PR @larsbonczek

We are currently in a project with 2I2C (CC @damianavila) to make this functionality more widely accessible. We will give an update on how to migrate as soon as we know more.
