• Fix finally There are some issues with the latest version #6
• Fix problem with already defined behat test steps by switching behat class to use traits
  (thank you, Jason Platts)
• Removed setting: fallbackspantag
  • It was not observed correctly (markup in the editor is still
    applied even if the setting was off).
  • Correcting the first point would have lead to no styling which
    is somewhat awkward when there are <span class="multilang">
    tags contained in the text but not marked as such (because
    of the setting being disabled).
• In Site administration -> Plugins -> Text editors the label for this plugin settings uses
  now the same language key as the plugin name itself (the "settings" suffix vanished).
• Add ci workflow for Moodle 4.3 and adapt behat test that used the source view of TinyMCE.
