chore: Fix dogfooding automation

[ncreated]

What and why?

🧰 💊 Fixes the recent problem with dogfooding script:

❌ Failed to dogfood: 'repositoryURL'
------------------------------------------------------------
Traceback (most recent call last):
  File "/Users/vagrant/git/tools/distribution/dogfood.py", line 119, in <module>
    dogfood(
  File "/Users/vagrant/git/tools/distribution/dogfood.py", line 76, in dogfood
    repository_url=dependency['repositoryURL'],
                   ~~~~~~~~~~^^^^^^^^^^^^^^^^^
KeyError: 'repositoryURL'

How?

The dependency['repositoryURL'] is not valid syntax for version 2 and version 3 Package.resolved. Updating the key name to location fixes the problem.

🎁 As a bonus, I added a basic smoke test for dogfooding automation. By running it with dry-run mode we ensure that it works fine after any change to dogfooding.py.
