Broken link in function documentation

[micokoch]

I counted 9 functions that have the same broken link (e.g., create_round) that says:

For more details consult the [documentation on tasks.json Hub config files](https://hubdocs.readthedocs.io/en/latest/format/hub-metadata.html#hub-model-task-metadata-tasks-json-file).

I assume the new, correct link should be:
https://hubdocs.readthedocs.io/en/latest/user-guide/model-metadata.html#template-metadata-schema-file

But, I'm not sure, as it seems insufficient in providing documentation for all those functions.
