Closes #526 | Add dataloader for WIkiHow-GOSC

[elyanah-aco]

Closes #526.

Notes:

• gdown is used to download from GDrive, see Closes #206 | Add Dataloader SleukRith Set #556 and Closes #531 | Add Dataloader Multilingual-ALPACA #566 for similar implementations.
• Only source schema is implemented is done after discussing with Holy.

Checkbox

• Confirm that this PR is linked to the dataset issue.
• Create the dataloader script seacrowd/sea_datasets/{my_dataset}/{my_dataset}.py (please use only lowercase and underscore for dataset folder naming, as mentioned in dataset issue) and its __init__.py within {my_dataset} folder.
• Provide values for the _CITATION, _DATASETNAME, _DESCRIPTION, _HOMEPAGE, _LICENSE, _LOCAL, _URLs, _SUPPORTED_TASKS, _SOURCE_VERSION, and _SEACROWD_VERSION variables.
• Implement _info(), _split_generators() and _generate_examples() in dataloader script.
• Make sure that the BUILDER_CONFIGS class attribute is a list with at least one SEACrowdConfig for the source schema and one for a seacrowd schema.
• Confirm dataloader script works with datasets.load_dataset function.
• Confirm that your dataloader script passes the test suite run with python -m tests.test_seacrowd seacrowd/sea_datasets/<my_dataset>/<my_dataset>.py or python -m tests.test_seacrowd seacrowd/sea_datasets/<my_dataset>/<my_dataset>.py --subset_id {subset_name_without_source_or_seacrowd_suffix}.
• If my dataset is local, I have provided an output of the unit-tests in the PR (please copy paste). This is OPTIONAL for public datasets, as we can test these without access to the data files.

hi @elyanah-aco, I checked this data, and some of the examples don't have any sections key (probably single-sectioned data).

This is an example of the key list of the data and (note: one-based index since I enumerate it from 1).

Do you mind making some readjustments on the _generate_examples to cater to such cases? I'm thinking of transforming such data into a section field with a single-valued list (let me know if you have a better workaround). Thx!

[elyanah-aco]

@sabilmakbar I'm thinking like this:

"sections": ["section": "", "steps": ['" Mulailah membuat situs web.", "Gunakan Twitter."], "ordered": 1],
"ordered": 1

where ordered inside and outside sections are the same. ordered inside sections indicates if steps inside that section are ordered, and ordered outside indicates if sections themselves are ordered. They should be the same if there's just one section

[sabilmakbar]

I think for the outer ordered, it should be valued as 1, even if the inner section ordered value is 0 (the one coming from actual data) because it's a single-valued list anyway (indicates the list contents is ordered for sections data). The ordered in inner section (for section data, singleton list) will follow the initial ordered value from actual example. Wdyt?

If we're taking the example from prev ss (but the ordered value is 0 instead of 1), we can construct it like this:

# the `ordered` value in sections list indicatest the actual `ordered` state on the `steps`
"sections": ["section": "", "steps": ['" Mulailah membuat situs web.", "Gunakan Twitter."], "ordered": 0],
"ordered": 1 # the value indicates the ordering in `sections` is ordered (which is 1 for singleton list)

[elyanah-aco]

Yup you're correct. Will work on this tomorrow

lgtm!
