source integration: `build-draft-pull-requests` can not be altered until after `build-pull-requests` is enabled

Where on docs.platform.sh should be changed?

https://docs.platform.sh/integrations/source/gitlab.html#2-enable-the-integration
https://docs.platform.sh/integrations/source/github.html#2-enable-the-integration

What exactly should be updated?

When interactively creating an integration, if you select false for build-pull-requests, you are not prompted for any remaining build-* parameters. Our system for some reason then sets build-draft-pull-requests to true. In terms of activities this isn't an issue as we aren't building any PRs. However, if you then later want to enable build-pull-requests and disable build-draft-pull-requests you are unable to:

❯ platform integration:update -p <projectid> --fetch-branches=true --build-pull-requests=true --build-draft-pull-requests=false <integrationid>

  [ConditionalFieldException]                    
  --build-draft-pull-requests is not applicable  

According to @akalipetis the parameter build-draft-pull-requests can not be altered at all unless build-pull-requests is enabled. This means that a user must perform two actions: one to set build-pull-requests to true and then a second to update build-draft-pull-requests to false.

Further conversation, it appears that Platform sets build-draft-pull-requests to true as a default if build-pull-requests is set to false. This can be particularly confusing if, as a user, you've set up your integration interactively (as I've described above), go back to view your integration details to find that build-draft-pull-requests is "enabled". Further, because of the logic described above, you can not disable (set to false) build-draft-pull-requests until after you re-enable build-pull-requests.
