Component Devices table should only display LTS releases on Server entries

Using the above as an example, since Core doesn't apply to Server Certifications, there's no need to display Core columns on the Component Devices table.

As an added bonus, as we could be displaying LTSs for up to 10 years, we need space for up to 6 LTS columns
