Testing: upload workflows to WorkflowHub via API

[simleo]

Now that submitting RO-Crates is supported by the WorkflowHub API, we can programmatically upload the workflows we need for LM testing and get rid of tests/config/registries/seek/data.tar.gz.

A workflow can be submitted as follows:

import requests
from pathlib import Path

crate_archive = "/tmp/crate.zip"
hub_url = "http://localhost:3000"
api_key = "???"
proj_id = "1"

# upload workflow
headers = {"authorization": f"Token {api_key}"}
with open(crate_archive, "rb") as f:
    payload = {
        "ro_crate": (Path(crate_archive).name, f),
        "workflow[project_ids][]": (None, proj_id)
    }
    r = requests.post(f"{hub_url}/workflows", headers=headers, files=payload)
r.raise_for_status()
    
# update access policy
wf_id = r.json()["data"]["id"]
headers.update({
    "Content-type": "application/vnd.api+json",
    "Accept": "application/vnd.api+json",
    "Accept-Charset": "ISO-8859-1",
})
payload = {
    "data": {
        "id": wf_id,
        "type": "workflows",
        "attributes": {
            "policy": {
                "access": "download",
                "permissions": [
                    {
                        "resource": {"id": proj_id, "type": "projects"},
                        "access": "edit"
                    }
                ]
            }
        }
    }
}
r = requests.patch(f"{hub_url}/workflows/{wf_id}", headers=headers, json=payload)
r.raise_for_status()

This requires a recent WorkflowHub image.
