Bump/1.19

Note for myself in the future :

• on deploy, upgrade mongo to v5.X (a dump + import with savior is enough)
• upgrade two plugins :
  • nodebb-plugin-ns-awards-recalbox
  • Error: Route.post() requires a callback function but got a [object Undefined]
  • nodebb-plugin-s3-uploads-updated-again@0.4.0
  • TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string or an instance of Buffer or URL. Received undefined
