Every provider should have "data to vuln object" unit test

[willmurphyscode]

What would you like to be added:

Every provider has unit tests that assert that it can process a representative sample of records - completeness of our ability to process provider data is asserted at the unit test level.

Why is this needed:

We recently had some bugs merged into vunnel that should have failed unit tests - this issue exists to track getting the test coverage high enough.

Additional context:
The recent failure was in the debian provider, but we should check all the providers.

Providers:

• alpine chore: test alpine provider via snapshots #336
• amazon chore: add snapshot tests to Amazon provider #337
• centos
• chainguard chore: test chainguard provider via snapshots #339
• debian Add snapshot tests to debian provider #318
• github Add GHSA snapshot tests #346
• mariner Add Mariner snapshot tests #347
• nvd Add snapshot tests for NVD provider #340
• oracle Add snapshot tests for oracle provider #341
• rhel Add RHEL snapshot tests #342
• sles Add SLES snapshot tests #343
• ubuntu Add Ubuntu snapshot tests #344
• wolfi Add Wolfi snapshot tests #345
