API Docs are Incorrect

[twavv]

I'm just going to give an example of a talk from JuliaCon 2019.

The documented type for submission_type is `string, but it's (apparently?) an object with translations based on locales.

  "submission_type": {
    "en": "Lightning Talk"
  }

Duration is documented to be a number, but it's actually a time-string.

  "duration": "00:10"

Additionally, which fields are optional is not well documented (a few fields mention in the description that they're Available if XYZ, but it would be nice to include that in the type (e.g. ?string) as well).

Thank you for the feedback! I adjusted the documentation so that multi-lingual strings are marked as such.

The incorrect duration field is a bug that I will also fix, to be included in the next release.
