vc.el provides a 'repository-url that some backends implement.  By
parsing the repository-url I guess you can extract the owner and repo
name.  The repository-url can be obtained with something along the lines
of

(let* ((name (buffer-file-name))
       (backend (vc-backend name)))
  (when backend
    (vc-call-backend backend 'repository-url name)))

Obtaining the current branch seems a little harder.  Judging from
describe-function there doesn't seem to be a function in vc-git that
exposes the current branch.  But it should be easy to get by shelling
out to git.
