[andrefmello91]

Use shapely default way for creating a circle.

Thanks for this improvement @andrefmello91! I have left one comment for you to consider while finalizing 😃

Thanks for this @mortenengen!
I brought back npoints with the default value of 20 in the last commit.

Thanks for the fix, @andrefmello91. I noticed now that the PR was setup to merge with main instead of dev, and therefore our pipeline with code format, linting and testing was not triggered. A local run of the pipeline shows that all is good except for one test of a large circular section. I will unfortunately not have time to look into this before the coming week, but please feel free to explore the issue further and propose a solution 😃

Please note that I have pushed a commit that formats the code and adds a note in the docstring of CircularGeometry about the number of points being rounded to the nearest multiple of 4. So before committing and pushing any changes, you should first pull.

Sorry for making the PR in the main branch.
I checked the error, but at the moment I could not figure what is causing it.

No worries 😄 I will have a closer look the coming week.
