Modify Guild Onboarding parameters are all optional, but documented as required

[GnomedDev]

Description

Title sums it up. The documentation linked below currently says that all arguments to this endpoint are required when the API seems to accept partial requests similar to other Modify endpoints.

discord-api-docs/docs/resources/Guild.md

Lines 1333 to 1340 in 3b0b05e

	###### JSON Params
	| Field | Type | Description |
	|---------------------|-----------------------------------------------------------------------------------------------------------------|------------------------------------------------------------|
	| prompts | array of [onboarding prompt](#DOCS_RESOURCES_GUILD/guild-onboarding-object-onboarding-prompt-structure) objects | Prompts shown during onboarding and in customize community |
	| default_channel_ids | array of snowflakes | Channel IDs that members get opted into automatically |
	| enabled | boolean | Whether onboarding is enabled in the guild |
	| mode | [onboarding mode](#DOCS_RESOURCES_GUILD/guild-onboarding-object-onboarding-mode) | Current mode of onboarding |

This also brings into question why it is using PUT, instead of PATCH, but I may be missing something there.

Steps to Reproduce

For example, onboarding can be enabled by using the following cURL command, even though the documentation would lead you to believe that you had to fetch the onboarding object, mutate it, then call the modify endpoint with the whole object.

curl 'https://discord.com/api/v9/guilds/698223755582898207/onboarding' \
  -X 'PUT' \
  -H 'authorization: token' \
  -H 'content-type: application/json' \
  --data-raw '{"enabled":true}'

Expected Behavior

The API rejects the call with an error requiring all fields to be present, or the documentation is updated.

Current Behavior

The API accepts a partial object, when the documentation says it doesn't.
