processing a batch bundle entries in the audit log should contain version info

[d0roppe]

Is your feature request related to a problem? Please describe. when audit is active for a fhir server, when processing a batch bundle the version of the resource processed should be in the audit entry. today we do not do this, we only have it on a single put. not on a batch bundle put.

might apply to transaction bundles too

Consider updating the e2e audit tests to invoke the fhir history endpoint and then confirm that we have a corresponding audit event in kafka for each interaction.
