pull request closing references #1128

I wonder whether there is a supported way to parse/retrieve references to issues/pull requests from pull request body descriptions like github.com supports using e.g. closes #123

all official keywords are described on https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/using-keywords-in-issues-and-pull-requests

I would love to either parse the pr body description or call a api endpoint to get a list of referenced issues from a given PR
