Sort package vulnerability advisories by severity in descending order

[jebriede]

Bug

Fixes: NuGet/Home#11091

Regression? Last working version: N/A

Description

Sort the list of vulnerabilities when the PackageSearchMetadataContextInfo is created so the list is cached in order and already in order whenever it is used. Since the list is in order with the highest severity vulnerability at the top, calculate the maximum severity by looking at the first vulnerability to save on computation time of checking for the max in the list.
