py-traitlets: doesn't support Python 3.6 in version 5

Log message:
py-jupyter_core: updated to 4.7.1

4.7.1

- Allow creating user to delete secure file (:ghpull:`213`)

4.7.0

- Add a new ``JUPYTER_PREFER_ENV_PATH`` variable, which can be set to switch the \ 
order of the environment-level path and the user-level path in the Jupyter path \ 
hierarchy (e.g., ``jupyter --paths``). It is considered set if it is a value \ 
that is not one of 'no', 'n', 'off', 'false', '0', or '0.0' (case insensitive). \ 
If you are running Jupyter in multiple virtual environments as the same user, \ 
you will likely want to set this environment variable.
- Drop Python 2.x and 3.5 support, as they have reached end of life.
- Add Python 3.9 builds to testing, and expand testing to cover Windows, macOS, \ 
and Linux platforms.
- ``jupyter --paths --debug`` now explains the environment variables that affect \ 
the current path list.
- Update the file hidden check on Windows to use new Python features rather than \ 
ctypes directly.
- Add conda environment information in ``jupyter troubleshoot``.
- Update ``_version.version_info`` and ``_version.__version__`` to follow Python \ 
conventions.

Log message:
pytest from versioned deps.

Log message:
py-jupyter_core: updated to 4.6.3

4.6.3
- Changed windows secure_write path to skip all filesystem permission checks \ 
when running in insecure mode.
  Too many exception paths existed for mounted file systems to reliably try to \ 
set them before opting out with the insecure write pattern.

Log message:
py-jupyter_core: updated to 4.6.2

4.6.2
- Add ability to allow insecure writes with JUPYTER_ALLOW_INSECURE_WRITES \ 
environement variable
- Docs typo and build fixes
- Added python 3.7 and 3.8 builds to testing

Log message:
py-jupyter_core: updated to 4.6.1

4.6.1
- Tolerate execute bit in owner permissions when validating secure writes
- Fix project name typo in copyright

Log message:
py-jupyter_core: updated to 4.6.0

4.6.0
- Unicode characters existing in the user's home directory name are properly
  handled.
- mock is now only required for testing on Python 2.
- Deprecation warnings relative to _runtime_dir_changed are no longer
  produced.
- The scripts directory relative to the current python environment is
  now appended to the search directory for subcommands.
- Some utility functions (exists(), is_hidden(), secure_write())
  have been moved from jupyter_client and jupyter_server to
  jupyter_core.
- Fix error on Windows when setting private permissions

Log message:
Use https for jupyter.org.

Log message:
py-jupyter_core: updated to 4.5.0

4.5.0
- jupyter --version now tries to show the version number of various other
  installed Jupyter packages, not just jupyter_core.
  This will hopefully make it clearer that there are various packages with
  their own version numbers.
- Allow a :envvar:JUPYTER_CONFIG_PATH environment variable to specify a
  search path of additional locations for config.
- jupyter subcommand no longer modifies the :envvar:PATH environment
  variable when it runs jupyter-subcommand.
- Jupyter's 'runtime' directory no longer uses XDG_RUNTIME_DIR.
  While it has some attractive properties, it has led to
  various problems; see the pull request for details.
- Fix JupyterApp to respect the raise_config_file_errors traitlet.
- Various improvements to the bash completion scripts in this repository
- The setup.py script now always uses setuptools, like most other Jupyter
  projects.
- The LICENSE file is included in wheels.
