test: fix duplicate schema test cases (#267)

Before this change, we had duplicated tests (with the same YAML, just
with different file name), see e.g.:

https://github.com/typesafegithub/github-actions-typing/blob/ca1309fb40c902b61865f1768b8d03cd4d3a12e6/src/test/resources/bad-typings/inputs_integer_list_item_with_non_integer_named_value.yml

# Testing

```
find src/test/resources | grep ml | xargs md5 -q | sort | uniq -c | sort -n | grep -v " 1 "
```

returns nothing.
