Feature: Optionally display date

[ClementValot]

Following the recent supply chain attacks through npmjs, I figure it would be interesting to optionally display the publish date of the returned packages

I already tested that the npmMinimalAgeGate prevents recent enough packages from being displayed, but the additional info would be a step further in prevention.

I didn't get into the source code yet so I don't know whether it'd be a costly feature.

What do we think about this?

I like it, if it's available from the registry should be an easy addition. Would definitely accept a PR!
