The version parsing logic for OpenJDK releases is a bit of a minefield, where sometimes the prefix is relevant and sometimes not. This fix isolates ignoring of the prefix to just matching of *-pool records in Backports.java. I'm reusing the same regex that already existed for doing something similar in that class. The previous usage was in the logic for the hgupdate-sync label.

Yeah, this is a minefield 😨 I can't say that your change is obviously correct, but at least the existing tests and your new test is passing and the newly added logic corresponds to your reasoning. But whether that is the end of OpenJDK version parsing is hard to say 🤷
