UI: display a badge when the npm package is deprecated

Description

When the npm package is deprecated it'd be great to reflect that on the UI. Maybe display a new badge.

Proposal

backend

• Add new value deprecated to the status enum.
• Make sure we set the status to deprecated when the package is deprecated and update it back when the package is undeprecated.
• Create the background migration to update the status to deprecated for existing deprecated packages.

frontend

• Uses the status deprecated to display the badge near the package's title on the list and details page.
• Add another option in the status filter dropdown called deprecated to filter by deprecated packages.
