a11y: Add accessibility to some Ubuntu pages
requested to merge Sergio.Costas/gnome-initial-setup:a11y-add-accessibility-support-for-main-ubuntu-pages into ubuntu/latest
This patch adds full accessibility support to these three ubuntu specific pages:
- Welcome to Ubuntu
- Ubuntu report
- Final page (more applications)
Now these pages are correctly read by Orca whenever they are shown.
It also merges in the same patch the one that adapts the drawing style to the currently used.
It is marked as Draft to allow desktop team to review it first.
