[Request]: document watching a whole store/mutable

What is this request related to?

Request

📋 Suggested

Need some docs on how to watch a whole store (all keys).

📋 General description or bullet points

It's not obvious how to do this. See this Google search result example:

The first result links to the Stores page where it could be documented:

https://docs.solidjs.com/concepts/stores

A better API would be nice, one that is an officially documented function:
