Add `latest_released_at` column to catalog_resources table

What does this MR do and why?

This is a migration to add the latest_released_at column to the table catalog_resources. This column is a date-time type and is nullable. It will be used to contain the latest released_at date from the Catalog Resource's valid Releases (aka "Versions").

The purpose of this column is to allow for more efficient sorting of Catalog Resources based on each of their latest Release's released_at date.

Resolves the first step of #408382 (closed).
