Release Moodle app version 3.9.5

Tasks to be done every time we are going to release a new version: https://docs.moodle.org/dev/Moodle_Mobile_release_process

• Accessibility improvements to achieve WCAG 2.1 AA compliance
• H5P improvements (play packages using as much screen as possible and improve the way they are embedded)
• New Moodle 3.11 student completion support
• LTI 1.3 launch support
• iOS ITP settings support (to allow the iOS version of the app to embed content from different URLs)
• New option in iOS for allowing the user to open a file using the system Preview or a dedicated app
• Plagiarism information display available in essay question types
• Word count support in quiz essay questions
• Display quiz pass grade on quiz front page

In this version, we've also upgraded the framework we use for building the app (Ionic upgraded to version 5). Unfortunately, there are several changes that might impact plugins or sites using their own custom mobile CSS.

• If you have developed a plugin that is supported for the mobile app please read: Adapt your Mobile plugins to Ionic 5

• If you have a Premium app subscription and your own Moodle App theme please read: Ionic5 style migration guide
