[JSTEP-11] Change 3.0 to use `module-info.java` directly (and not via Moditect)

[cowtowncoder]

In Jackson 2.x we use Moditect plugin to add module-info.class, instead of relying on javac. This because build is done using JDK 8 which cannot handle module-info.java.

But with Jackson 3.0 using JDK 17 or above we can and should convert.

NOTE: all modules should do this, except for jackson-annotations which remains JDK 8 built for now.

I think module-info.class needs to be put in META-INF/versions/11 (or 9). I'm not sure if fb5ad1b would do that.

Not sure why -- minimum JDK for master/3.0 is JDK 17. Do you have a link to something that explains possible reasons to do so? (docs I saw just talked about src/main/java/ (and src/test/java for test version)

But either way I think it's shade plugin that is somehow filtering/not-copying module-info.class, regardless of where it needs to go.

You are probably right - that the module-info.class only needs to be in META-INF/versions when you still support Java 8.
