Creating Pull Request doesn't take fork behavior into account

[sergiou87]

The problem

Using Branch -> Create Pull Request from a fork, will open the browser to create the PR in the parent repo, even if the fork behavior is set to "For my own purposes": https://github.com/desktop/desktop/blob/eeec2730468db2adb14256bca01002c7532dc963/app/src/lib/stores/app-store.ts#L6041-L6058

Release version

3.1.2

Operating system

macOS Monterey 12.6

Steps to reproduce the behavior

1. Fork a repository
2. Set its fork behavior to For my own purposes
3. Create a branch
4. Commit some changes
5. Click on Branch -> Create Pull Request

You'd expect to be creating a PR to your fork repo, but instead you will create it in the parent repo.
