Fluid2D's tool scripts are broken

[kBlankii]

Describe the bug

After attaching either "fluid_2d_circle.gd" or "fluid_2d_rectangle.gd" to a Fluid2D node and changing its size parameter (circle_radius / height & width) in the inspector, the Godot IDE outputs the following error message:

ERROR: Cannot call GDExtension method bind 'create_circle_points' on placeholder instance.
ERROR: Cannot call GDExtension method bind 'set_points' on placeholder instance.

To Reproduce

Just by following the steps in the official documentation.

Expected behavior

After editing circle_radius in the inspector, a circle should be appearing in the scene editor without any error thrown.

Environment:

• OS: Windows 10
• Version: 22H2 19045.5965
• Godot Version: 4.4.1 stable
• Type: godot-rapier-2d-single-simd-parallel
