Release of PyExasol 2.2.0

I am happy to announce release pyexasol 2.2.0 on GitHub and pypi.

Pyexasol already supported prepared statements before while this update adds an explicit method to create prepared statements.
For more details, check out their example usage on the Examples page of the User Guide.
File poetry.lock was updated to handle vulnerable main & transitive dependencies.
To ensure usage of secure packages, it is up to the user to similarly relock their dependencies.
