fix: version info nil on version api endpoint

[zcmack]

This fix resolves #2337 and ensures the proper version number is included on the /version api endpoint. As per the discussion in the issue, it sources this data from driver\config\buildinfo.go and shows "master" when run locally / in docker.

Further Comments

I didn't add a test because I didn't see testing of the /health or /version endpoints outside of tls_termination_test.go but that doesn't seem like a logical place to put a simple payload validation test. Can certainly add one if an approach is recommended. No documentation changes as this is a bugfix and doesn't alter expected behaviors or processes.
