/*
	TestFetchRealCommunity is not actually a test, but an utility to check the community description in all of the store nodes.
	It's intended to only run locally and shouldn't be executed in CI, because it relies on connection to the real network.

	TODO: It would be nice to move this code to a real utility in /cmd.
		  It should allow us to fairly verify the community owner and do other good things.

	To run this test, first set `runLocalTests` to true.
	Then carefully set all of communityID, communityShard, fleet and other const variables.

	NOTE: I only tested it with the default parameters, but in theory it should work for any configuration.
