Steps to reproduce

• Use the @feathersjs/mongodb adapter as a datasesource adapter for your project
• Add the operator to the queryable fields in the TypeBox querySchema as follows

export const tagQuerySchema = Type.Intersect(
    [
        querySyntax(tagQueryProperties, {
            title: {
                $regex: Type.Any()
            }
        }),
        // Add additional query properties here
        Type.Object({}, { additionalProperties: false })
    ],
    { additionalProperties: false }
)

• Query the collection with the following query

app.service('tags').find({
  query: {
    title: {
      $regex: /(?:)/i
    }
  }
})

Expected behavior

As per the latest docs, specifying the operator in the querySchema is sufficient to allow custom operators call, without the need to add the option operators: ['$regex'] to the service adapter options.

The query should return the documents that have a title that match this regex expression.

Actual behavior

Instead we get this error error: BadRequest: Invalid query parameter $regex.

Only when I add the operators option (which is marked as deprecated) it works fine.
