Shapely 1.8 is old unmaintained. We originally had to introduce it to nixpkgs in
order to package kikit, but recently kikit upstream dropped the
requirement to use an old version of shapely
(https://github.com/yaqwsx/KiKit/issues/574#issuecomment-1879721181).
Upstream relaxed the version constraint in
3427a8d6ce,
which first landed in kikit 1.5.0, which we're already packaging, so
we're free to drop shapely 1.8!
This includes support for KiCad 8 (see complete changelog
[here](https://github.com/yaqwsx/KiKit/releases/tag/v1.5.0)), which should unblock
https://github.com/NixOS/nixpkgs/pull/291134.
With this upgrade, a test started failing:

This is failing in some pretty old kikit code, so I think this is just
failing due to kikit now having more complete code coverage. While
researching this, I discovered kikit's documentation about [optional
dependencies], which I suppose we don't have good support for right now.
Rather than invent a new option for that, I've opted to preserve the
existing behavior and just do the bare minimum to keep the build
passing.
