Include audit info when loading table from Polaris

[bryanck]

This PR includes table audit information in load table responses for Polaris, even when the flag to only include metadata location is present. The audit information is already loaded and does not require loading the Iceberg table. Also it is relatively small, so should have a negligible impact on performance.

Adding this allows us to capture audit fields in batch without loading the Iceberg table, for example, when running our table inventory process.

• Add or update a unit test to verify that auditInfo is correctly populated when includeMetadataLocationOnly is true, to prevent regressions in this new behavior.

                        .auditInfo(info.getAudit())

• Update the JavaDoc for this method or branch to document that auditInfo will now be included when includeMetadataLocationOnly is enabled, ensuring the behavior is clear to future readers.
