Web API changes:
- `/get` endpoint:
- Removed `status` from JSON object - now uses HTTP response codes `200` if the target url was resolved correctly or `404` otherwise.
- Missing HCards are now serialized as null instead of an empty dict


json5
// https://example.org/webmention/get?url=my-article
// Old 1.x.x response
{
"status": 1,
"target_url": "https://example.org/my-article",
"mentions": [
{
"hcard": {},
"quote": null,
"source_url": "https://another-example.org/their-article",
"published": "2020-01-17T21:45:24.542Z"
}
]
}


json5
// https://example.org/webmention/get?url=my-article
// New 2.0.0 response with HTTP status 200 (or 404 if target_url does not exist)
{
"target_url": "https://example.org/my-article",
"mentions": [
{
"hcard": null,
"quote": null,
"source_url": "https://another-example.org/their-article",
"published": "2020-01-17T21:45:24.542Z"
}
]
}
