Using any keyword together with nil causes panic in generated code

[Link512]

Description

Using any keyword and returning nil does not generate the same code as for interface{}, causing a nil interface panic

Mockery Version

2.46.1 - does NOT reproduce with previous versions

Go Version

1.23.1

Installation Method

• Binary Distribution
• Docker
• brew
• go install
• Other: [specify]

Steps to Reproduce

1. Define an interface with a method returning any

type Foo interface {
	WithAny() any
	WithInt() interface{}
}

2. Make that method return nil

func TestFoo(t *testing.T) {
	fooMock := mocks.NewFoo(t)

	fooMock.EXPECT().WithInt().Once().Return(nil)
	fooMock.EXPECT().WithAny().Once().Return(nil)

	_ = fooMock.WithInt()
	_ = fooMock.WithAny() // panics
}

Expected Behavior

Code doesn't panic

Actual Behavior

Code panics.

Upon inspecting the generated code, I've noticed that the two mocked methods differ in how they handle the return:

// for interface{}
if ret.Get(0) != nil {
     r0 = ret.Get(0).(interface{})
}

// for any
r0 = ret.Get(0).(any)

Indeed! I'll have to look into this, this should be a simple fix.
