[DOC] Data Fetching page link to DataProvider interface is broken

[BenMusch]

Documentation issue

On this page: https://refine.dev/docs/guides-concepts/data-fetching/

The docs say:

To manage data, Refine needs a data provider, which is a function that implements the DataProvider interface.

However, the link (https://refine.dev/docs/core/interface-references/#dataprovider) is broken. While the interface-references page exists, there is no #dataprovider element and no documentation on the DataProvider interface

Describe the thing to improve

The link should go somewhere useful or not exist

Describe the solution (optional)

Either the DataProvider interface should be documented and linked, or this sentence should be re-written. I am new to this project so I'm not sure if the issue is that this interface does exist and is undocumented or if it doesn't exist at all

Hey @BenMusch thanks for the report! We'll check it and get back to you.

We are accepting pull requests for this one. The task is as simple as adding DataProvider interface definition to interface-references page in our documentation.
