Allow examples when auto documenting workflow

Currently, commands remove spacing and newlines when creating the documentation from the docstring. This prevents adding examples to the documentation.

E.g.
```
Runs the Benchmark on a specified model.

**Example:**

```{python}
# running a model on all languages and tasks
seb run sentence-transformers/all-MiniLM-L6-v2 -o results.json

# Running a model on a subset of languages
seb run sentence-transformers/all-MiniLM-L6-v2 -o results.json -l da sv no nn

# Running a model on a subset of tasks
seb run sentence-transformers/all-MiniLM-L6-v2 -o results.json -t DKHate ScaLA
```

Becomes:

```
Runs the Benchmark on a specified model. Example: ```{python} # running a model on all languages and tasks seb run sentence-transformers/all-MiniLM-L6-v2 -o results.json # Running a model on a subset of languages seb run sentence-transformers/all-MiniLM-L6-v2 -o results.json -l da sv no nn # Running a model on a subset of tasks seb run sentence-transformers/all-MiniLM-L6-v2 -o results.json -t DKHate ScaLA
```

A potential fix is to remove the `_strip` command to avoid removing newlines.
