Log in json format

[finestructure]

When using the

  log: json

directly, the output is

JSON: [["web_url": "https://gitlab.com/finestructure/swiftpackageindex-builder/-/pipelines/246973893",
"updated_at": "2021-01-26T13:51:50.448Z", "ref": "main", "created_at": "2021-01-26T12:56:28.027Z", 
"id": 246973893, "sha": "fe40569a07afe8c2d6c5fd6327161cb1221baf0e", "status": "running"], ["created_at

It would be better to log this real json format, for further processing, and in a way that supports redirects.
