Wrong is_freshness_enabled on stg_sources when warn_after is missing

[cos-pet-learn]

Describe the bug

Sources are flaged with is_freshness_enabled = false when warn_after is not configured, but error_after is configured

Steps to reproduce

I have configured freshness at source level:

version: 2

sources:
  - name: sdqn
    freshness:
      error_after:
        count: 168
        period: hour

Expected results

is_freshness_enabled = true in stg_sources for all tables in that source

Actual results

is_freshness_enabled = false in stg_sources for all tables in that source
