Remove unused variable in editor_properties.cpp

[ASamBlur]

After #108065 there is no need to declare the hint variable here.

godot/editor/inspector/editor_properties.cpp

Lines 4106 to 4111 in 1559ab3

	case Variant::BASIS: {
	EditorPropertyBasis *editor = memnew(EditorPropertyBasis);
	EditorPropertyRangeHint hint = _parse_range_hint(p_hint, p_hint_text, default_float_step);
	editor->setup(_parse_range_hint(p_hint, p_hint_text, default_float_step));
	return editor;
	} break;

If it compiles it compiles. _parse_range_hint has no side effects either.
