/**
 * Disables pagination when `query.$limit` is `-1` or `'-1'`.
 * Removes the `$limit` from the query and sets `params.paginate = false`.
 * Must be used as a `before` or `around` hook on the `find` method.
 *
 * @example
 * ```ts
 * import { disablePagination } from 'feathers-utils/hooks'
 *
 * app.service('users').hooks({
 *   before: { find: [disablePagination()] }
 * })
 * // Then call: app.service('users').find({ query: { $limit: -1 } })
 * ```
 *
 * @see https://utils.feathersjs.com/hooks/disable-pagination.html
