Since T365147: CommunityConfiguration: Support minimum / maximum validation constraints for JSONSchema, MediaWiki-extensions-CommunityConfiguration makes it possible for extensions such as GrowthExperiments to specify minimum/maximum value for numbers and integers. This can be used to improve user experience by disallowing negative numbers for fields where negative numbers do not make any sense, such as Maximum number of links to show per task in https://es.wikipedia.beta.wmflabs.org/wiki/Especial:CommunityConfiguration/GrowthSuggestedEdits.
Within this task, we should review all usages of TYPE_NUMBER and TYPE_INTEGER in GrowthExperiments, and consider whether they need a minimum/maximum set, or whether any number is okay. As part of this task, we should only consider technical concerns (rather than product ones) – for example, we would be fine with any positive number for Maximum number of links to show per task (although including 200 links in a single task is likely not desirable from product PoV).
