fix(ingest/bigquery): fix and refractor exported audit logs query

[mayurinehate]

Earlier when audit logs were exported in date sharded table format, the timestamp where clause was incorrectly constructed as

as

        timestamp >= "20230328"
    AND timestamp < "20230328"

instead of

        timestamp >= "2023-03-28T09:29:00Z"
    AND timestamp < "2023-03-28T10:01:00Z"

giving error Could not cast literal "20230328" to type TIMESTAMP
