Title:
  changelogs not listed for PPA packages

Status in update-manager package in Ubuntu:
  Fix Released
Status in update-manager source package in Noble:
  Fix Released

Bug description:
  * Impact

  When clicking on a package from a PPA in update-manager, the "Changes
  for XXX versions:" section will say:

  "This update does not come from a source that supports changelogs."

  Which seems a side effect of https://blog.launchpad.net/ppa/new-
  domain-names-for-ppas , the code filter on ppa.launchpad.net in the
  url where those are using ppa.launchpadcontent.net now

  * Test case

  - enable a ppa including an update for a package you have installed
  - start update-manager and select that package
  - check the long description at the bottom
   
  it should display the changelog entry for the update

  * Regression potential

  The change is in the _extract_ppa_changelog_uri() function so a
  potential issue would impact updates coming from a ppa. Verify that
  those are correctly listed and include a valid description

  -----------------------------------------------

  The reason is that in _extract_ppa_changelog_uri() in
  /usr/lib/python3/dist-packages/UpdateManager/Core/MyCache.py it checks
  only for ppa.launchpad.net but nowadays the URI will contain
  ppa.launchpadcontent.net instead.

  With the below patch it will correctly display the changelogs:
