GH-476: Assemble Zip for Javadocs

Fixes: https://github.com/spring-projects/spring-retry/issues/476

* Add `maven-assembly-plugin` to Zip Javadocs from the `apidocs` dir into a `*-docs.zip` artifact
* Modify `build-and-deploy-snapshot.yml` and `release.yml` to assign `zip.deployed=false` attribute to Zip artifacts
* Also mark `docs.zip` files as `zip.type=docs`
