#12888
Updated code so that macOS version returns RSR, if available. For
example: `14.3.1 (a)` as opposed to simply `14.3.1`
This feature is supported by osquery with the `extra` column in
`os_version` table.
Since I could not get a real macOS running a version with RSR, I did the
following manual checks:
- ensured that `extra` column from osquery `os_version` table was being
received for processing
- hard coded the `extra` column result on the server and verified the OS
version was correct in GUI and REST APIs
Main testing was done by Zach following these
[instructions](https://docs.google.com/document/d/18xsCEFlpcBL-5EbQhvmUNuJz3XM0Ak-NfCCwxEQXVic/edit)
- I confirmed that the one incorrect query result was due to a bad query
