Increment the manifest for the latest Data API Builder version manifest

[stephlocke]

The manifest of versions (the link in the constant) being referenced has version 1.3.19 as the latest version however we're now at 1.5.* - please could you update this constant with the latest available manifest and perhaps collab with the dat aapi builder team to ensure they update it on a timely basis for you?
