docs: update references from setup.py to pyproject.toml

Update documentation, comments, and docstrings throughout the codebase
to reflect the migration from setup.py to pyproject.toml:

- Transformer class docstrings: changed to reference "entry point name
  in the package configuration" for better future-proofing
- Block structure module docs: updated to reference pyproject.toml
- Test file comments: updated entry point references
- Config files (tox.ini, pytest.ini): updated references
- Documentation (extension_points.rst, course apps ADRs): updated to
  reference pyproject.toml with inclusive language for external packages
- Requirements documentation (github.in): updated with inclusive language
- edxmako README: modernized install command to use pip install

Historical ADRs and references to external packages that may still use
setup.py were intentionally left unchanged or updated with inclusive
language acknowledging both pyproject.toml and setup.py.
