F1 score not calculated properly

### Describe the bug

According to the [definition](https://en.wikipedia.org/wiki/F-score) of the F1 score for two classes, it can be calculated as 

$$
2 \frac{2tp}{2tp + fp + fn}
$$

or 

$$
2 \frac{precision * recall}{precision + recall}
$$

From what I can see, scikit-learn [uses](https://github.com/scikit-learn/scikit-learn/blob/38a06e4be504f3971d109d6741b8b4c7192d7323/sklearn/metrics/_classification.py#L1764C11-L1764C11) some variant of the second definition. The problem is that the first definition can be valid, while the second gives a division by zero as the precision is not defined.

$$
precision = \frac{tp}{tp + fp}
$$

$$
recall = \frac{tp}{tp + fn}
$$

For definitions of precision and recall, see [Wikipedia](https://en.wikipedia.org/wiki/Precision_and_recall). 

Below, I give a code example where this happens.

### Steps/Code to Reproduce

```python
from sklearn.metrics import f1_score, precision_score, recall_score
import sklearn.metrics
import numpy as np

y_true = [True, False, True]
y_pred = [False, False, False]

tn, fp, fn, tp = sklearn.metrics.confusion_matrix(
    y_true, y_pred, labels=[False, True]
).ravel()

print("TN:", tn)
print("FP:", fp)
print("FN:", fn)
print("TP:", tp)

precision = tp / (tp + fp)
recall = tp / (tp + fn)
print("Precision:", precision)
print("Recall:", recall)

f1_true = 2 * tp / (2 * tp + fp + fn)
print("F1 (true):", f1_true)

f1_sk = f1_score(y_true, y_pred, zero_division=np.nan)
print("F1 (sklearn):", f1_sk)
```

### Expected Results

```
TN: 1
FP: 0
FN: 2
TP: 0
Precision: nan
Recall: 0.0
F1 (true): 0.0
F1 (sklearn): 0.0
```

### Actual Results

```
TN: 1
FP: 0
FN: 2
TP: 0
<ipython-input-1-d59969af6bb0>:17: RuntimeWarning: invalid value encountered in scalar divide
  precision = tp / (tp + fp)
Precision: nan
Recall: 0.0
F1 (true): 0.0
F1 (sklearn): nan
```

COMMENT:
I unfortunately don't have the time to learn the scikit-learn codebase and to propose a solution. I am reporting the issue here and then someone who actually knows the codebase can provide a solution that would work, be consistent with how all other similar functions work, don't have unintended side effects etc.
