fix: add the missing GNOME Core apps to "yafti" template

- Added missing apps. The list is now synced with upstream's list of Core apps (https://apps.gnome.org/). Minus the few that Fedora doesn't ship by default (such as Console, Music, Web, etc).

- Names that are already installed at the native system-level (such as Nautilus) are not included in the list.

- Fixed the names of a few apps.

- Two of the newly added apps have names that have a high risk of confusing new users, so they were added as "Photos (Organizer)" and "Videos (Player)" to avoid confusion from newcomers, otherwise they might think that those checkboxes add some bundled photos or video files.
