Post release fixes

[robaru]

There are a few things that should be done/improved now that the code is public.

Quick

• README.md
  • broken readthedocs link (it is bayesian-listener, not bayesian_listener)
  • reference to AMT, add link
• in documentation, add a clear link to GitHub
• advance copyright with year (maybe make it automatic?)
• add guide to CONTRIBUTING.rst bugs and patches: create branch, do change, commit, update history, bump my version, bump-my-version bump patch --verbose --dry-run (to test it, remove --dry-run), pull request on main, when tests pass: rebase

Long

• create repo with notebooks for paper replication with paper figures
  • run notebooks with code in development
  • [ ]
