Note: I asked the bot for help because the documentation [here](https://wiki.openjdk.org/display/SKARA/Pull+Request+Commands#PullRequestCommands-/backport), along with examples [here](https://github.com/openjdk/jdk/pull/8205#issuecomment-1153856655) and [here](https://github.com/openjdk/jdk/pull/4128#issuecomment-873779183), seem to imply that backport is not a valid command for closed PRs, so I wanted to know what my options were.

I mean, options aside from the somewhat lengthier process detailed [here](https://wiki.openjdk.org/display/SKARA/Backports), which I'll do if I must.
