fix: add format field to integration test packageOptions and regenerate docs

The --format flag was added to the package command but:
1. Integration tests constructed packageOptions directly without setting
   format, causing validation to fail with 'invalid --format value ""'
2. Reference docs were not regenerated after adding the new flag

Set format: "docker" in all three test packageOptions structs and
regenerate docs with 'make docs'.
