fix: allow pr checkout from non-default repository (#827)

When working in a mulit-remote pull requests may come from separate
repositories.

Octo currently lets you list and view PRs from a configurable
repository.
However, when it comes to checking out a review branch, it only looks at
the current default repository via `gh cli`.

This change simply provides the PR's repository string to `gh pr
checkout` command so non-default repository branches can be checked out
as well.

Prior to this commit if you did something like `Octo pr edit 1234
owner/repo-b` where `repo-b` is not the default repository and tried to
start a review, the PR branch would not be checked out, since its in the
non-default repository.
