apt info does not show the Supported: information for 20.04 LTS kernels

[Jeff Lane ]

One of our cert tests has been failing on Focal kernels. Lookning at the -29 kernel today, we noticed that the Supported: item is missing when looking at Apt info.

This change was made by a bot.

[Andy Whitcroft (apw)]

This was an intentional change. As the release pocket in immutable we end up with inaccurate information in the pocket if the support time changes for a package, such as happens when we enter ESM. There is/will be tooling to find the support lifetime. Part of this is the ubuntu-security-status command.
