repo Field in PullRequest

[alexanderles]

I'm working with the PullRequest struct and noticed the repo field, which I don't see in the Github API documentation (https://docs.github.com/en/rest/pulls/pulls?apiVersion=2022-11-28).

When using octocrab, I'm finding that this field is always None in the responses that I receive for my use cases so far. I've mainly been using the PullRequest struct to hold info I get from listing pull requests (https://docs.rs/octocrab/latest/octocrab/pulls/struct.PullRequestHandler.html#method.list) and I currently only get valid Repository values from the repo fields that are nested under base and head of PullRequest.

Is there something else the top level repo is used for? In what cases could I expect a value for this field?
