Bug with `ShapeSolver` and `Circle`

[Jammy2211]

I was trying to use the ShapeSolver to compute points within a Circle.

When I used this API:

        centre = self.source_plane_centre.in_list[0]

        triangles = solver.solve_triangles(
            tracer=self.max_log_likelihood_tracer,
            shape=aa.Circle(y=centre[0], x=centre[1], radius=0.3)
        )

I did not compute solutions which matched the PointSolver, but instead were quite different.

When I use this API (swapping y and x I get a good solution:

        centre = self.source_plane_centre.in_list[0]

        triangles = solver.solve_triangles(
            tracer=self.max_log_likelihood_tracer,
            shape=aa.Circle(y=centre[1], x=centre[0], radius=0.3)
        )

Digging into the Circle object, I think the problem is that grids are (unintuitively) defined where index [0] is y and index [1] is x, however the Circle object defines them the other way round.

Thus, the use of Circle in certain calculation is likely incorrect.
