Feature: Inspect versions of all packages in each asset

[step2yeung]

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 :)
