Docstring fixes

[tms-bananaquit]

• Double-check the formatting on the numbered list in make_example_data.make_example_batch_data
• docs/source/examples/convert_notebooks.py docstring should include a note that it must be run from within a subdirectory of the cloned repo.
• Update the release number on conf.py to the appropriate version, or remove the release number from conf.py entirely, if RTD/sphinx allows it.
• Remove this line from the README: "A flowchart breaking down these contexts can be found on the ReadTheDocs page under “Choosing a Detector.”"
  • The page was removed, but the docstring update was not.
• Add this to the CHANGELOG.md
