Update default apps

It looks like you've got this based on your previous branch instead of master, so since we already merged your previous PR, there are now conflicts. I can fix this for you. I assume it's okay if I just discard all changes to the Live Disk article and photos?

In the future, you can git checkout master (and git pull) before creating a new branch to avoid this.

Thank you, I changed branches and did git pull first, sorry. I will make sure to do git checkout master and git pull before the new branch.

No worries. I fixed this by doing git rebase -i master (-i stands for --interactive) and then deleting the commit from the previous PR from the list.

This is a much more useful article than what was there before (the old one really didn't need to be a support article).

I moved some of the content around to better separate the intro from the configuration section, and re-ordered the list of apps to flow from left to right in the dock.

This is really nice update to the default applications for COSMIC. Running the site live, no odd rendering.

Linter was mad about the very last line. There were two errors: one for a bare link and one for using ** bold ** instead of a heading. I think I fixed it.
