Title:
  "ReleaseNotesViewer" does not display anything with the text view

Status in ubuntu-release-upgrader package in Ubuntu:
  Fix Released
Status in ubuntu-release-upgrader source package in Groovy:
  New
Status in ubuntu-release-upgrader source package in Hirsute:
  New
Status in ubuntu-release-upgrader source package in Impish:
  Fix Released

Bug description:
  When upgrading with do-release-upgrade the ReleaseAnnouncement, e.g.
  http://archive.ubuntu.com/ubuntu/dists/hirsute/main/dist-upgrader-
  all/current/ReleaseAnnouncement, should be displayed. This works with
  DistUpgradeViewGtk3 but not DistUpgradeViewText.

  [Test Case]
  1) run 'do-release-upgrade -d -f DistUpgradeViewText' in a terminal on an Ubuntu 21.04 or Ubuntu 20.10 system
  2) you will see a sudo password prompt after the release upgrader tarball is downloaded (i.e. after the message "extracting '$nextrelease.tar.gz'")

  After installing ubuntu-release-upgrader from -proposed you'll see the
  text of the ReleaseAnnouncement before the download of the release
  upgrader tarball and a "Continue [yN]" prompt.

  Additional test:
  1) run 'do-release-upgrade -d -f DistUpgradeViewGtk3' in a terminal with the -proposed version of ubuntu-release-upgrader
  2) confirm that you don't see the ReleaseAnnouncement in the terminal

  [Where Problems Could Occur]
  This is new code in DistUpgradeFetcherCore.py for the showReleaseNotes() function. This function also exists in DistUpgradeFetcher.py so the additional code should not affect it but as a regression test "do-release-upgrade -d -f DistUpgradeViewGtk3" should also be run in a terminal to ensure that the ReleaseAnnouncement file is not shown in the terminal and in a GUI dialog.
