PoissonRegressor lbfgs solver giving coefficients of 0 and Runtime Warning

### Describe the bug

See the following [stack exchange](https://stats.stackexchange.com/questions/622085/sklearn-poissonregressor-giving-all-coefficients-zero) post (the solution to my original issue was to use newton-cholesky solver)

When fitting a Poisson Regression (without regularization) to some dummy data I encounter:

- with lbfgs solver, a Runtime Warning, a non-zero intercept and all coefficients as zero
- with newton-cholesky solver, coefficients as expected

Some people on StackExchange have mentioned it is worth submitting an issue (there was a similar [one](https://github.com/scikit-learn/scikit-learn/issues/24752) faced with Logistic Regression).

### Steps/Code to Reproduce

```python
import statsmodels.api as sm
import statsmodels.formula.api as smf
import pandas as pd
from sklearn.linear_model import PoissonRegressor
from sklearn.preprocessing import (
    OneHotEncoder,
)
data = sm.datasets.get_rdataset('Insurance', package='MASS').data
# Fit Poisson regression using formula interface
formula = "Claims ~ C(District, Treatment(1)) + C(Group, Treatment('<1l')) + C(Age, Treatment('<25')) + Holders"
model_smf = smf.poisson(formula=formula, data=data).fit()
print(type(model_smf))
print(model_smf.summary())
# with sklearn OneHotEncoder

X_train_ohe = OneHotEncoder(sparse_output=False, drop=[1, "<1l", "<25"]).fit(data[["District", "Group", "Age"]])
X_train_ohe = pd.DataFrame(X_train_ohe.transform(data[["District", "Group", "Age"]]), columns=X_train_ohe.get_feature_names_out())

X_train = pd.concat([X_train_ohe, data[["Holders"]]], axis=1)
y_train = data["Claims"]

# one-hot encode the categorical columns, and drop the baseline column
# with lbfgs solver

model_sklearn_lbfgs = PoissonRegressor(alpha=0).fit(X_train, y_train)

print(model_sklearn_lbfgs.intercept_)
print(model_sklearn_lbfgs.coef_)
# with newton-cholesky solver

model_sklearn_nc = PoissonRegressor(alpha=0, solver='newton-cholesky').fit(X_train, y_train)

print(model_sklearn_nc.intercept_)
print(model_sklearn_nc.coef_)
```

### Expected Results

Expected intercept/coefficients (from statsmodels and sklearn with newton-cholesky solver):
```
2.8456859090224444
[-4.47436243e-01 -9.30629212e-01 -1.46547942e+00  1.00603354e+00

  2.22504699e+00 -1.58161172e-05]
```

### Actual Results

Result with lbfgs:
```

COMMENT:
We could indeed force numpy to raise an exception during the matmul and rewrap it with a `ValueError` with a more informative error message.

```python
with np.errstate(all='raise'):
    # do the matmul here
    ...
```
