[DOC] BaseForecaster score function uses MAPE instead of sMAPE as metric
#### Describe the issue linked to the documentation

The [score function](https://github.com/sktime/sktime/blob/ed4efe9e47fa998ad6b21d63b0ac58f932ab1b3f/sktime/forecasting/base/_base.py#L1234C1-L1234C1) of the BaseForecaster suggests the metric that is used for evaluation is sMAPE:

```
Returns

        -------

        score : float
            sMAPE loss of self.predict(fh, X) with respect to y_test.
```
            
The code calls the [mean_absolute_percentage_error function](https://github.com/sktime/sktime/blob/ed4efe9e47fa998ad6b21d63b0ac58f932ab1b3f/sktime/performance_metrics/forecasting/_functions.py#L1448) without any further parameters. 

```     
from sktime.performance_metrics.forecasting import (
            mean_absolute_percentage_error,
        )

        return mean_absolute_percentage_error(y, self.predict(fh, X))
``` 

But the default values of the [mean_absolute_percentage_error function ](https://github.com/sktime/sktime/blob/ed4efe9e47fa998ad6b21d63b0ac58f932ab1b3f/sktime/performance_metrics/forecasting/_functions.py#L1448) are: 

```
def mean_absolute_percentage_error(
    y_true,
    y_pred,
    horizon_weight=None,
    multioutput="uniform_average",
    symmetric=False,
    **kwargs,
):
```

and the doc states:

```
... 
    symmetric : bool, default=False
        Calculates symmetric version of metric if True.
...
```

Thus I conclude that instead of the sMAPE, MAPE is returned.

#### Suggest a potential alternative/fix

Either adjust the documentation such that it states that the MAPE metric is used or adjust the implementation by adding the symmetric parameter. I did not investigate if there are other places with the documentation error. ;) Many thanks!!
