Unsafe usage of PyYAML yaml.load()

[gkmr507]

The default behavior of PyYAML's yaml.load() method is unsafe and can execute code in yaml files.
yaml.safe_load() should be used instead:yaml/pyyaml#193 (comment)

design-tokens/utils/automatic-release/lib/defineVersion/index.js

Line 20 in 7a53823

const latestContent = yaml.load(latestPath);
