API Docs have wrong properties for platform type / enum

[pavog]

Observed/problematic behavior

The automatically generated openapi specification file for Hangars API contains an error for the Platform type.
It is defined the following way:

    Platform:
      maxLength: 3
      minLength: 1
      type: string
      description: Server platform
      example: PAPER
      enum:
      - PAPER
      - WATERFALL
      - VELOCITY

The problem here are: maxLength and minLength.
These two properties simply do not belong here.
It also makes it impossible to use the download endpoint (/api/v1/projects/{slug}/versions/{name}/{platform}/download) using the ui for the api-docs (https://hangar.papermc.io/api-docs#/Versions/downloadVersion).

See the attached screenshot:

Expected behavior

I should be able to choose all 3 platforms (PAPER, WATERFALL or VELOCITY) on the UI and don't get an error.
The properties maxLength and minLength for Platform should not be in the generated open api specification file.

Steps to reproduce

1. Go to https://hangar.papermc.io/api-docs#/Versions/downloadVersion
2. Click "Try it out"
3. Enter a project slug. Example: ViaVersion
4. Enter a version name. Example: 4.8.0-1.20.2-pre1-SNAPSHOT+14
5. Choose a platform. Example: PAPER
6. Click "Execute"
