Added test

Suggestions for python-pillow#8085

• I've added a test
• I've moved the ImageDraw.circle() documentation up, to maintain the (mostly) alphabetic order.
• I've updated the release notes, and it now links to the other parts of the documentation. You can see what it would look like at https://pillow-radarhere.readthedocs.io/en/imagedraw_circle/releasenotes/10.4.0.html.
