[Added] Amend URL Link For Humanitarian Clusters (Sector Vocab codelist)

The URL link for code 10 Humanitarian Global Clusters on the Sector Vocabulary codelist is no longer valid due to a change of domains on the third party hosting site. The URL link therefore should be replaced with the following link https://data.humdata.org/dataset/standard-cluster-names-and-codes/resource/24b50d16-897b-46f9-848b-7fce08ac599b

The IATI tech team have reviewed and approved this amendment to URL link. The link has been updated.
