Release new versions of example projects

[ucodery]

The versions on pypi.org have not kept up to date with what is in the project, and neither has isort's pyproject.toml. This currently blocks updating the lock file:

SolverProblemError

  The current project's Python requirement (>=3.6.2) is not compatible with some of the required packages Python requirement:
    - example-isort-sorting-plugin requires Python >=3.6,<4.0, so it will not be satisfied for Python >=4.0

  Because example-isort-sorting-plugin (0.0.3) requires Python >=3.6,<4.0
   and no versions of example-isort-sorting-plugin match >0.0.3,<0.0.4, example-isort-sorting-plugin is forbidden.
  So, because isort depends on example_isort_sorting_plugin (^0.0.3), version solving failed.

because of #1877

I would like to apply this diff, but can't as poetry then complains that the specified dependency doesn't match any versions.

The change to isort's python dependency seems to have really messed up the ability to do a poetry update. I'm not sure how a new lock file was generated for #1877 but if I clear poetry's cache and then run a poetry update it won't solve because requirements of isort also declare python dependency with a caret range and, as noted in that issue, poetry does not allow mixing greater-than and caret ranges, even when they overlap.

Besides all the example isort project (actually all three need adjusted), the following won't solve with isort's dependency on python>=3.6:

• portray
• cruft
• hypothesis-auto

As an infrequent user of poetry maybe I am missing something, but seems that either isort needs to restore the ^3.6 or drop some of these requirements.

@staticdev We could also consider just removing these examples projects? They don't seem that useful anymore?
