chore: exclude if TYPE_CHECKING: lines from coverage reporting

[rich-iannone]

This addresses a pyOpenSci reviewer comment related to test coverage reporting. The recommendation was to exclude if TYPE_CHECKING: lines from coverage reporting since the condition is always False at runtime. This is done here globally through the addition of a .coveragerc file.

Fixes: #547
