Revert Go module subfolder move and bump to v0.37.0 (open-telemetry#567)

Next steps to resolving the failed `v0.36.0` release mentioned at open-telemetry#566 
- Revert folder change from open-telemetry#413
- Add `retract` directive for `github.com/open-telemetry/otel-arrow
v0.36.0`
- Bump version number to `v0.37.0` for a clean release with the
retraction
