Use `yaml.full_load_all` instead of `yaml.load_all` (#13577)
Use `yaml.full_load_all` instead of `yaml.load_all` (#13577)

Calling `yaml.load_all()` without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.

`yaml.full_load_all` instead use load_all() with Fullloader
