keepQuery does not keep '$' query fields

Steps to reproduce

[keepQuery('field'), disablePagination()] does not work since keepQuery removes $limit

Expected behavior

keepQuery should either keep dollar query fields or a new hook should be provided.

Why don't you use this: [keepQuery('field', '$limit'), disablePagination()] ?

I think a callback would be useful. Something like: [keepQuery((key) => key.startsWith('$'), 'field'), disablePagination()]. Are you up to add this change?
