Fix #2974.

When an arc has rx or ry equal to 0, the path code replaces it with a line to the arc's end point. That end point is already absolute at this point (it's converted for a just above), but the replacement used the relative l command, so the line was drawn to the wrong place. It now uses L.

Added test_path_a_zero_radius: a rectangle drawn with two zero-radius arcs (one with rx = ry = 0, one with only rx = 0). It fails without the fix and passes with it. tests/draw/svg/test_paths.py passes.

I used an AI assistant to help draft parts of the code and tests; I reviewed the changes and ran the tests myself.

Sorry, I opened this as a draft by mistake, and GitHub doesn't let me mark it as ready for review. Could you switch it to ready? It's ready to be reviewed.
