refactor: remove `lodash`

[G-Rath]

What did you implement:

Removed lodash as a required dependency for this plugin.

How did you implement it:

I replaced the single usage of lodash with a native equivalent, and then I removed it from dependencies in package.json

How can we verify it:

❯ rg --files-with-matches 'lodash'
integrationTests/configurations/node16-linux-webpack/package-lock.json

If lodash was being used by this package, then there should have been a match in either a TypeScript or JavaScript file, which there was not.

The tests also will fail if lodash is actually still needed.
