Enforce defaults in deps ingest pull request configuration

[JAORMX]

Summary

If the user would forget to set the parameters, the deps ingest would
fail saying that the filter is invalid. This is not ideal for the user
since we should just set reasonable defaults.

This fixes that!

We now default to new_and_updated if no filter configuration is set.
