typo in UnparsedSourceDefinition.__post_serialize__

[abuckenheimer]

Haven't actually run into a bug from this yet but was just perusing the source code and noticed this:

https://github.com/dbt-labs/dbt/blob/85627aafcd7fcd1a2a1c61b13348ced1b52571d4/core/dbt/contracts/graph/unparsed.py#L271

Have to imagine freshnewss is a typo

@abuckenheimer I have to imagine you're right :)

Care to make that one-line fix?

Still there!

dbt-core/core/dbt/contracts/graph/unparsed.py

Lines 288 to 290 in ba23395

	if 'freshnewss' not in dct and self.freshness is None:
	dct['freshness'] = None
	return dct

Going to mark this a good first issue
