flatcam: do not pin setuptools in shapely

[tjni]

Description of changes

In the 1.8.x branch of shapely, setuptools was pinned to less than 64 because of a bug the maintainers were seeing related to Windows tests (shapely/shapely#1481). We don't have that problem, and in fact we are on a newer version of setuptools. Once we migrate to build, this version constraint will start failing the build.

I suggest that we update the version of shapely as per this comment. #249847 (comment)
However, a major update is required and needs to be checked.

I found this while drowning in the sea of PR.

Merging this first to unbreak the build. Will follow up on updating it.
