Bug description:
  * Impact

  If Pro is not enabled, then the details pane against a Pro update
  misleads the user into believing that there is no update available.

  Example of someone being misled:
  https://inteltechniques.com/blog/2023/11/12/ubuntu-pro-shenanigans/

  Expected results: either no details presented, or the actual details
  of the potential Pro update presented

  Actual results: a message that implies that there is no update
  available for this package, Pro or not.

  * Test Case

  Install the update on a system not attached to Pro, select an update
  in the Pro section, check the 'Version available' string, it should
  reflect the version that would be installed if pro was enabled

  * Regression potential

  The change is in the code getting the available version to display, if
  the logic was wrong it could lead to have the 'available version'
  label being missing or incorrect. The code could hit an exception if
  there was not non expected value
