Use Pip to setup Khoj in Docker, Github Workflows. Publish to PyPi Automatically

### Details
#### Github Workflows
- Make Github Workflows use `pip` instead of `conda`
- Publish Khoj as Python Package Automatically
   - Version based on [PEP440](https://peps.python.org/pep-0440/) and [Semantic Versioning](https://semver.org/) specs
   - On Push to Master: Publish a pre-release (alpha) to PyPI
   - On Push to PR: Publish a development-release on TestPyPI
   - On creating a (release) tag: Publish the latest version (Major.Minor.Patch) to PyPI
#### Docker 
   - Make `Dockerfile` use `pip` to build image for Khoj. Faster, more standard flow than `conda`
   - Only Build Docker Image on Push to Master
      - Availability of pip package negates the need for docker image for PR testing 
   - Make Docker-Compose use Docker Image published to Github Container Registry
- Default Image search to disabled. [Fix loading CLIP model](https://github.com/UKPLab/sentence-transformers/issues/1659) before re-enabling
