message: docs(api): Remove readme reference to obsolete CLI calibration tool

  -------------
  The module has a lot of configuration, some of which is only relevant when running on an actual robot, but some of which could be useful during simulation. When the module is first imported, it will try and write configuration files in ``~/.opentrons/config.json`` (``C:\Users\%USERNAME%\.opentrons\config.json`` on Windows). This contains mostly paths to other configuration files and directories, most of which will be in that folder. The location can be changed by setting the environment variable ``OT_API_CONFIG_DIR`` to another path. Inividual settings in the config file can be overridden by setting environment variables named like ``OT_API_${UPPERCASED_VAR_NAME}`` (for instance, to override the ``serial_log_file`` config element you could set the environment variable ``OT_API_SERIAL_LOG_FILE`` to a different path).

  -Using the Deck Calibration Tool
  --------------------------------
  -
  -You can run this tool from the command line of the robot by using ``ssh`` to access the terminal.
  -To run the tool either type ``calibrate`` or ``python -m opentrons.deck_calibration.dc_main``
  -
  -Instructions:
  - - Robot must be set up with two ``300ul`` or ``50ul`` single-channel pipettes
  - installed on the right-hand and left-hand mount.
  - - Put a GEB ``300ul`` tip onto the pipette.
  - - Use the arrow keys to jog the robot over slot ``5`` in an open space that
  - is not an engraving or a hole.
  - - Use the ``q`` and ``a`` keys to jog the pipette up and down respectively
  - until the tip is just touching the deck surface, then press ``z``. This
  - will save the ``Z`` height.
  - - Press ``1`` to automatically go to the expected location of the first
  - calibration point. Jog the robot until the tip is actually at
  - the point, then press ``enter``.
  - - Repeat with ``2`` and ``3``.
  - - After calibrating all three points, press the space bar to save the
  - configuration.
  - - Optionally, press ``4``, ``5``, ``6`` or ``7`` to validate the new configuration.
  - - Press ``p`` to perform tip probe. Press the space bar to save again.
  - - Press ``m`` to perform mount calibration. Press the space bar to save again.
  - - Press ``esc`` to exit the program.
