Feature: Inspect versions of all packages in each asset

I have a use case where we want to inspect versions of all the packages bundled in each asset.

The `version` action currently reports on multiple versions of packages installed that have version skews and have 2+ files included in the bundle. Could we add a new plugin to report all versions in the bundle?
eg:
```
new VersionsPlugin({
verbose: false
})
```

Happy to discuss more & take on the work :)
