Story (Required)
As an OpenShift user, I'd like to see the LATEST charts, sorted by release (semver) version.

But today the list is in the order they were released, which makes sense if your chart is single-stream, but not if you are releasing for multiple product version streams (1.0.z, 1.1.z, 1.2.z)

Background (Required)
RHDH has charts for 2 concurrent release streams today, with a 3rd stream coming in June, so we'll have 1.0.z updates after 1.2, and 1.1.z after that. Mixing them together is confusing, especially with the Freshmaker CVE updates.

Acceptance Criteria
One of two implementations:

a) default sorting is by logical semver, with latest being the bottom of the list (default selected) and top of the list being the oldest chart; or

b) UI to allow choosing to sort by release date or version
