Update Space to dataset storage docs

[Wauplin]

This PR updates the "Data Persistence for Spaces" section (here and here) to showcase CommitScheduler instead of Repository with this example Space and this guide.

The documentation is not available anymore as the PR was closed or merged.

I'm not 100% sure about this change. The schedule commit setup is nice but a bit complex to set up compared to just repository. Should we add a simple commit example to the guide?

The schedule commit setup is nice but a bit complex to set up compared to just repository.

Maybe it is the docs/Space that are not simple enough which makes it looks as a complicated setup. Because IMO it really isn't that complex to use CommitScheduler as long as you don't care about the data format (e.g. being compatible with dataset-preview). Complexity about the data format is the same with the scheduler or a git clone since it's a matter of "how to save the data".

Basically, the setup goes from

repo = Repository(
    local_dir="data/", clone_from=DATASET_REPO_URL, use_auth_token=HF_TOKEN
)
repo.push_to_hub()  # on every call

to

scheduler = CommitScheduler(
    repo_id=DATASET_ID, repo_type="dataset", folder_path="data/", token=HF_TOKEN
)
