structured data on codebase landing pages + codemeta integration

[alee]

Each codebase release should have its own specific CodeMeta associated with it. Embed structured json-ld data in the landing page, and provide it in the downloaded archive.

The root object is an instance of https://schema.org/SoftwareSourceCode

• add a targetProduct that is an instance of https://schema.org/SoftwareApplication
• provide additional properties where possible, for example the SoftwareSourceCode discussionUrl should point to the related Discourse comments page this would require some hacking since the discourseEmbed is generating that link..
• add softwareRequirements properties based on captured dependencies (from stencila/dockta?)

[alee]

discussionUrl can be set by querying the discourse endpoint /embed/info

Example:

curl 'https://meta.discourse.org/embed/info?embed_url=https://blog.discourse.org/2021/04/discourse-team-grows-to-50' -H 'API-KEY: logapikeygoeshere' -H 'API-USERNAME: apiusernamehere' 

Response:

{
  "topic_id": 187794,
  "post_id": 925017,
  "topic_slug": "discourse-team-grows-to-50-blog",
  "comment_count": 2
}

The embed_url should be the permanent_url for the codebase landing page, and the response we get can be parsed for the topic_id to generate a forum.comses.net/t/<topic_id> link to include as the discussionUrl.

add dedicated sponsors and funding fields to Codebase metadata as well as emitted codemeta
