`jar xf <jar> <path>` doesn't expand glob patterns in <path> the way
`unzip` does — paths must be exact. My initial script passed
`BOOT-INF/lib/jpdfium-natives-darwin-x64-*.jar` as a literal path,
which matched nothing, so the script always reported
"No JPDFium darwin natives in bootJar; nothing to sign" and exited
without actually signing anything.
Fix: `jar tf` to LIST the bootJar's contents, grep with a regex for
the snapshot-versioned native-jar paths, then `jar xf` those exact
paths.
The natives jars are normally:
BOOT-INF/lib/jpdfium-natives-darwin-x64-1.0.0-SNAPSHOT.jar
BOOT-INF/lib/jpdfium-natives-darwin-arm64-1.0.0-SNAPSHOT.jar
…but the version number floats with the snapshot timestamp, hence
the regex match instead of a fixed path.
