🚀 Feature Proposal

Re-export some (all?) types from mongodb package.

Motivation

Currently there's no way of using most of the types included in this plugin's mongodb dependency as they're not re-exported from the plugins type declaration files (I think only ObjectId is being re-exported), to make use of those types it is necessary to install the mongodb package as a dev dependency of the whole project.
I want to write a helper function to parse some queryString parameters and create a mongodb query object, currently the only way to make this type safe is to add mongodb as a dev dependency of the project and import the types from it, but this makes the project end up with two installations of the module (maybe even different!).

Example

import type { Filter } from '@fastify/mongodb' <--- This should be possible
// import type { Filter } from 'mongodb' <--- This shouln't be necessary

function filterParser(obj?: FilterSchema) {
  const filter: Filter<Event> & Record<string, unknown> = {
    active: true
  }
  Object.entries(obj ?? {}).forEach(([k, v]) => {
    switch (k) {
      case 'title':
      case 'summary':
      case 'description':
        if (typeof v === 'string') {
          filter[k] = { $regex: v, $options: 'i' }
        }
        break
        ...
