"int64 indices" error in fit_predict function even with 32-bit integer

### Describe the bug

I'm trying to apply spectral clustering on a sparse adjacency matrix of a surface mesh. Although the matrix's entries are using 32-bit integer indices, the `fit_predict` function gives me the following error: 
```
ValueError: Only sparse matrices with 32-bit integer indices are accepted. Got int64 indices. Please do report a minimal reproducer on scikit-learn issue tracker so that support for your use-case can be studied by maintainers.
```

### Steps/Code to Reproduce

```python
import trimesh
import pyvista as pv 
import numpy as np
import networkx as nx
from sklearn.cluster import SpectralClustering 

# Get a sample file
bunny = pv.examples.download_bunny_coarse()
vertices = np.array(bunny.points) # (num_vertex, 3)
faces = bunny.faces.reshape(-1,4)[:, 1:] # trinangular faces, (num_face, 3)

# Create a mesh object in trimesh
mesh = trimesh.Trimesh(vertices=vertices, faces=faces)

def mesh_to_graph(mesh):
    G = nx.Graph()
    # Add nodes
    for i, vertex in enumerate(mesh.vertices):
        G.add_node(i, pos=vertex)
    # Add edges
    for face in mesh.faces:
        for i in range(3):
            G.add_edge(face[i], face[(i + 1) % 3])
    return G

def spectral_clustering_mesh(mesh, n_clusters=6):
    # Convert mesh to a graph
    G = mesh_to_graph(mesh)
    # Compute the graph adjacency matrix as a scipy sparse array 
    adj_matrix_sparse = nx.to_scipy_sparse_array(G, dtype=np.int32, format='csr')
    # Perform spectral clustering 
    sc = SpectralClustering(n_clusters = n_clusters,
                            affinity='precomputed',
                            assign_labels='kmeans')
    labels_groups = sc.fit_predict(adj_matrix_sparse) # <--- Causes the error! 
    return labels_groups

# Run the clustering 
labels_groups = spectral_clustering_mesh(mesh, 6)

# Use the labels groups to color-code the mesh
pl = pv.Plotter()
pl.add_mesh(mesh, scalars=labels_groups, colormap=cm.Spectral_r)
pl.show()
```

### Expected Results

If successful, the code should find 6 clusters of facets and color-code the Stanford bunny accordingly. 

### Actual Results

COMMENT:
Hi,@lesteve, sorry to reopen this. Is there anyway we can cluster feature matrix that indeed has a nnz >'int32' range ?
I am trying to cluster long sentences with their ngram, when 'n' increase, it's easy to meet the problem.
