Data generator items report is not deterministic

The default item components report is not deterministic when running the data generator multiple times or between version. Expected behavior would be that the component types are sorted consistently.

An example diff can be seen on GitHub

How to reproduce

1. Run the data generator
2. Look at the reports/items.json file and copy it to another location
3. Run the data generator again
4. Notice that the order of the components is different
