QID 980769: Nodejs (npm) Security Update for js-yaml (GHSA-xxvw-45rp-3mj2)

Versions 2.0.4 and earlier of `js-yaml` are affected by a code execution vulnerability in the YAML deserializer.

## Proof of Concept
```
const yaml = require('js-yaml');

const x = `test: !!js/function >
function f() {
console.log(1);
}();`

yaml.load(x);
```

## Recommendation

Update js-yaml to version 2.0.5 or later, and ensure that all instances where the `.load()` method is called are updated to use `.safeLoad()` instead.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
