v2.0.22.2

📣 borb release 2.0.22.2

This release is a small bugfix release.
By adding al lot of imports to borb/pdf/__init__.py suddenly all imports for Chart were imported.
This included matplotlib.pyplot. This import is only needed when working with Chart.
I changed the code in Chart to only declare the type, but not do the import (as it didn't really need to in the first place).
