Updated `yaml.load` to `yaml.safe_load`

[KillDozerX2]

PyYAML's .load method has been deprecated without the use of a loader and detailed into a security vulnerability, many audit workflows and CI tests are failing and this module works without any issues with just safe_load, hence the commit. This can be read in detail on their wiki https://github.com/yaml/pyyaml/wiki/PyYAML-yaml.load(input)-Deprecation
