docs: Fix values for used recording consent options

[nickvergessen]

☑️ Resolves

• Fix Recording consent property is inconsistent  #13085
• The other part was a misunderstanding. I thought as we return the talkConfig value here it could be 2, but the 2 is the first part of the check which will return the room option:

  spreed/lib/Service/RoomFormatter.php

  Line 141 in 956a1ab

  'recordingConsent' => $this->talkConfig->recordingConsentRequired() === RecordingService::CONSENT_REQUIRED_OPTIONAL ? $room->getRecordingConsent() : $this->talkConfig->recordingConsentRequired(),

• OpenAPI for this part is in feat(openapi): Add more type/int limitations #12783 (comment)
