Update google-java-format to 1.24.0

[loosebazooka]

1.25.0+ require a minimum java build version of 17, so we can update to latest as we upgrade our build.

LGTM

What do you mean by 1.25.0+ require a minimum java build version of 17?

We currently use Java 17 for the build (still target 11).
We could even bump to "require Java 21 for the build" and still target --release 11.

I thought we still build with 11 in our matrix

No no no. We use the latest and greatest javac compiler, and we use --release 11 so it produces Java 11-compatible bytecode. This should reduce the number of bugs we face when we use old javac.

See #923

In practice, you could launch the build with ./gradlew -PjdkBuildVersion=21 jar to build the jars with javac 21.

I've moved pgjdbc to use javac 21 recently: pgjdbc/pgjdbc#3612, and it might be time to bump the build JDK for sigstore-java as well.

That's cool, isn't it?

oh yeah, I guess I vaguely recall this now
