Goal: Modeling's `separability_matrix` does not compute separability correctly for nested CompoundModels
Consider the following model:
```python
from astropy.modeling import models as m
from astropy.modeling.separable import separability_matrix
cm = m.Linear1D(10) & m.Linear1D(5)
```
It's separability matrix as you might expect is a diagonal:
```python
>>> separability_matrix(cm)
array([[ True, False],
[False, True]])
```
If I make the model more complex:
```python
>>> separability_matrix(m.Pix2Sky_TAN() & m.Linear1D(10) & m.Linear1D(5))
array([[ True, True, False, False],
[ True, True, False, False],
[False, False, True, False],
[False, False, False, True]])
```
The output matrix is again, as expected, the outputs and inputs to the linear models are separable and independent of each other.
If however, I nest these compound models:
```python
>>> separability_matrix(m.Pix2Sky_TAN() & cm)
array([[ True, True, False, False],
[ True, True, False, False],
[False, False, True, True],
[False, False, True, True]])
```
Suddenly the inputs and outputs are no longer separable?
This feels like a bug to me, but I might be missing something?
## Completed stages
- **setup**: fail
- Script: `git clone https://github.com/astropy/astropy.git . && git checkout d16bfe05a744909de4b27f5875fe0d4ed41ce607 && sed -i 's/requires = \["setuptools",/requires = \["setuptools==68.0.0",/' pyproject.toml && python -m pip install -e .[test] --verbose`
- Stdout:
```
fatal: destination path '.' already exists and is not an empty directory.
```
- Stderr: (empty)
## Context
- failure_class: deterministic
- failure_signature: setup|deterministic|script failed with exit code: <n> ## stdout fatal: destination path '.' already exists and is not an empty directory.
Fix this GitHub issue in the repository. Make the minimal code change needed.
