- Tag docker image with `tag_name' on release (i.e tag push)
- Else tag with 'pre' on push to master
- Else tag with 'dev' on push to PR branch
- Only tag the latest release with release tag
Previously the latest commit on master was being tagged with the
latest tag. This doesn't sync with the release cadence of the rest
of Khoj
- Add a productionized setup for the Khoj server using `gunicorn` with multiple workers for handling requests
- Add a new Dockerfile meant for production config at `ghcr.io/khoj-ai/khoj:prod`; the existing Docker config should remain the same
