release: kirby-sheet 0.2.1

Corrects what 0.2.0 shipped: kirby_sheet.__version__ reported "0.1.0" while
the distribution metadata said 0.2.0. A patch release because 0.2.0 is
immutable on PyPI and a wrong version string is the kind of thing another tool
reads and believes.

No behaviour change. Verified from the built wheel that the module attribute
and the distribution metadata now agree.
