Add PR Description as metadata

[asummers]

We can put the PR description via string or file, but this is not forwarded in the metadata, so we can't access it in steps without making a subsequent API call. It would be awesome if we had this available. Use case here is ensuring that an author updates the required steps in a PR template as a build failure.

I've just submitted #276 this morning and I've seen this feature is not complicated to implement. After documenting metadata further in #274, I've identified that the PR body/description is the only metadata field that was provided by the legacy jtarchie resource and not this one.

The GitHub API provides 3 variants for the PR description:

• body (String!): The body as Markdown.
• bodyHTML (HTML!): The body rendered to HTML.
• bodyText (String!): The body rendered to text.

I guess MarkDown would best fit you use-case for checking required steps have been updated in the PR description template. Can you confirm?

Unfortunately, there's no hope that you get any further support here (#246 was 2+y ago).

But recent news is that the Cloud Foundry community is now maintaining a fork of this resource at cloudfoundry-community/github-pr-resource.

In that new repo, the PR #277 that I had submitted here has been ported as cloudfoundry-community#8 and has been merged.

On our Concourse installation at Gstack, the latest version is working fine. Could you give a try and provide feedback there?

(the new resource is a drop-in replacement; you only have to switch telia-ossto cfcommunity in in the resource_types: declaration, i.e. specify repository: cfcommunity/github-pr-resource)

Now that PR cloudfoundry-community#8 is shipped with v0.25.0, could you please closed this issue @schmurfy? Thanks!
