Fix/examples custom operator downloads (#1945)

* Switch to master for download in 00-wrapping_numpy_capabilities.py

* Switch to master for download in 01-package_python_operators.py

* Change downloads.py/_retrieve_file to not restrict to basename, allowing to define subpaths

* Remove useless imports

* Switch to master branch for 02-python_operators_with_dependencies.py
