Simplify the packages list by consolidating versions of the package into the detail page

Background

This issue relates to the UX scorecard recommendations issue

Problem

It's difficult to search for a specific package when there are many entries on the package table to parse. Displaying a line in the table for each version of the package adds unnecessary noise to this screen:

Proposal - see designs attached to issue

Logic

• The most recent package version (by date) will be shown on the package list page
• if a package has more than 1 version, the number of versions are listed on the package list page

Image	Explanation
	If a package has multiple versions, show that after the most recent version on the package registry list page.
	If a package has only 1 version, show only the version number.

Notable changes from current implementation

Current implementation	Proposal	Reason
		Show only the author on the Right. Note that there is also a change to link the project. This can happen outside of this issue and is related to #349010 (closed)
		The most important information on the Other versions tab is the version

Future iterations

1. we improve it by showing latest release based on latest tag (a convention we decide to adopt). If there are no packages with the latest tag we fallback to time-based (iteration 1)
2. Then again we could improve this even further letting users decide what tags to look for when showing the latest package version and again, if no package version is found we fallback to time-based (iteration 1). By default we would use our convention, the latest tag
