Add documentation publish and preview workflows

[aaronsteers]

This PR does a bunch of things:

1. Create new preview and publish workflows for the pdoc docs site.
   • The preview job attaches all html files to the GitHub action - which you can then download and review locally.
   • The publish job publishes the site to GitHub Pages. It runs on all commits to main and can be manually kicked off from the Actions tab as a manual workflow.
2. Add a CONTRIBUTING.md page where I'm starting to collect all the info on how to maintain the repo.
3. Sightly improve readme contents and replace instances of AirbyteLib with PyAirbyte.
4. Fully remove the pattern of saving generated docs into the repo. The docs/generated path is now ignored by git.
5. Remove viztracer dependency for now, because it was causing weird failures.
