We received user feedback that the Spring Boot tutorial currently doesn’t work. Currently, the tutorial asks you to create the rock under `spring-boot-hello-world` but the packing fails because Rockcraft can’t find the project files. The current tutorial needs the user to create and pack the rock under `spring-boot-hello-world/maven-app` instead. This PR aligns the Spring Boot tutorial with its corresponding Charmcraft tutorial during the app creation stage, by setting the `path` to be `spring-boot-hello-world`. Since the directory creation is now handled by devpack-for-spring, this PR also removes the instructions to manually create the directory. Another piece of user feedback we received was that the VM freezes during the rock packing stage. Through testing, we determined that the minimum viable VM for this tutorial requires 2 GB of RAM. This PR updates `docs/reuse/tutorial/setup_edge.rst` so that the VM is created with 2 GB of RAM, acknowledging that this change will also affect some other tutorials in the project. --- - [X] I've followed the [contribution guidelines](https://github.com/canonical/rockcraft/blob/main/CONTRIBUTING.md). - [X] I've signed the [CLA](http://www.ubuntu.com/legal/contributors/). - [X] I've successfully run `make lint && make test`. - [X] I've added or updated any relevant documentation.
