New PR for Managing Apps Article

[HappyGelo05]

This update enhances the article on installing, updating, and removing applications for Pop!_OS. The content now includes updated instructions for both Pop!_OS 22.04 and 24.04, providing clearer guidance to users. The article has been enriched with new screenshots for each step, ensuring better visual support and a more intuitive understanding of the processes. Additionally, this revision incorporates any changes specific to the newer Pop!_OS 24.04 release, alongside detailed explanations of key features.

Good start. I reviewed just the 24.04-relevant portion to start with.

Since I rebased this PR, you'll need to run these commands before making any further changes:

git checkout app-management-article
git pull
git reset --hard origin/app-management-article

Let me know if you have any questions.

I've removed the sections about launching & pinning applications and switching between open windows, as they're pretty off-topic for this article. If explaining that stuff is really necessary, it can be a separate article.

I won't waste time redoing the rest of the screenshots, but I've redone the ones with the biggest opportunities for improvement.

As I've addressed all of my remaining feedback myself, I can approve this now.
