fix: check if dependencies & devDependencies exist before deleting dep (#30224)

## Current Behavior
`removeDependenciesFromPackageJson` tries to delete dep from `undefined`
if there is no `dependencies` or `devDependencies` in package.json

## Expected Behavior
First check if `dependencies` or `devDependencies` exists

## Related Issue(s)
Fixes #30222
