While QA-ing the "whats new" feature on staging, I noticed that there
was a bug in translating "free". I've updated the logic so it correctly
translates "core" to "free".

I also titlecased the package names in the data yaml files. As well as
swapped out "All" for a list of package names.

The issue found here would be resolved once the file linter is merged:

But as that is still under development I figured a small MR to fix the
problem is best for now.
