When you try to download a dataset that uses [biopython](https://github.com/biopython/biopython), like `load_dataset("InstaDeepAI/multi_species_genomes")`, you get the error:

```
>>> from datasets import load_dataset
>>> dataset = load_dataset("InstaDeepAI/multi_species_genomes")
/home/j.vangoey/.pyenv/versions/multi_species_genomes/lib/python3.10/site-packages/datasets/load.py:1454: FutureWarning: The repository for InstaDeepAI/multi_species_genomes contains custom code which must be executed to correctly load the dataset. You can inspect the repository content at https://hf.co/datasets/InstaDeepAI/multi_species_genomes
You can avoid this message in future by passing the argument `trust_remote_code=True`.
Passing `trust_remote_code=True` will be mandatory to load this dataset from the next major release of `datasets`.

ImportError: To be able to use InstaDeepAI/multi_species_genomes, you need to install the following dependency: Bio.
Please install it using 'pip install Bio' for instance.
>>> 
```

`Bio` comes from the `biopython` package that can be installed with `pip install biopython`, not with  `pip install Bio` as suggested.


This PR adds special logic to show the correct package name in the error message of ` _download_additional_modules`, similarly as is done for `sklearn` / `scikit-learn`  already.

There are more packages where importable module name differs from the PyPI package name, so this could be made more generic, like:

```
# Mapping of importable module names to their PyPI package names
package_map = {
    "sklearn": "scikit-learn",
    "Bio": "biopython",
    "PIL": "Pillow",
    "bs4": "beautifulsoup4"
}

for module_name, pypi_name in package_map.items():
    if module_name in needs_to_be_installed.keys():
        needs_to_be_installed[module_name] = pypi_name
```
