Warehouse does not warn about EOL apps when installing

[evanmohr]

• I have read the README.md document
• I am using the latest version of Warehouse
• I am using the Flatpak package of Warehouse
• I have not found any other opened issues on the same topic

Describe the issue in detail

I was recently looking at Fedora Flatpaks in Warehouse when I noticed that Fedora Flatpaks had two entries for Firefox, one called org.mozilla.firefox (up to date) and org.mozilla.Firefox (out of date). Fedora Flatpaks has org.mozilla.Firefox marked as EOL, but this is not shown in Warehouse.

If applicable, provide steps to reproduce the issue

1. Enable Fedora Flatpaks (or find an EOL app on Flathub)
2. Go to "Install Packages"
3. Click on remote that contains EOL app
4. Search for EOL app
5. Verify that there is no message warning about it being EOL
