Deprecated use of pyyaml's yaml.load function without a Loader argument

[evilsetg]

Since pyyaml version 5.1 the use of the yaml.load function without a Loader argument is deprecated and issues a warning. Since version 6.0 yaml.load does not work at all without a Loader argument.

It is recommended to instead use the yaml.safe_load function that uses the SafeLoader or yaml.full_load for the FullLoader that supports serialization but is a bit less safe.

There are two files that use the deprecated syntax:

• tests/run_yaml.py
• {{cookiecutter.repo_name}}/devtools/scripts/create_conda_env.py
