Update Pythons, workflows for Poetry 1.2.0 release (#7)

* Set bash as the default shell

This removes the necessity of specifying the shell for every step that
uses the shell.

* Use the install script from Poetry's website

* Include 3.10 in tests

* Remove 3.6 support, require >=3.7,<4

Poetry removed 3.6 support in 1.2.0, so we can't support
it here either. This was because 3.6's end-of-life was on December 23,
2021. For more information see:

python-poetry/poetry#5055
https://devguide.python.org/versions/
https://peps.python.org/pep-0494/

In addition to removing 3.6 support, we're moving this project to require Python >=3.7 and <4

* Use the new plugin add syntax

* Create a release GitHub Actions workflow

This will make it simpler to release versions in the future.

* Bump version to remove pre-release
