Upgrade Spring Boot to the latest version

[robertmcnees]

Update the guide to use the most recent Spring Boot version.

Files that require changes are:

initial/build.gradle
initial/pom.xml
complete/build.gradle
complete/pom.xml

I did make a pull request for upgrading this repo.
But I am wondering, why not using dependapod or renovate for this ?

EDIT: I have tried both dependapod and renovate on another (forked) spring-guide and found that renovate is much better in grouping together the changes (initial,complete,gradle,maven) for each dependency.

That means: you get just one merge request for updating spring-boot from 3.1.0 to 3.1.4 that includes the 2 subdirs (initial and complete) and in there both build.gradle and pom.xml. All in one merge request. dependapod seems to make 4 merge request in that case which sucks.

all you need to do is to add renovate by following these steps : https://github.com/renovatebot/tutorial

Hi @bodote . Thanks for the comment and the PR! I merged the PR.

I agree there are more automated ways to keep our dependencies up to date. For this project I want to keep the effort manual so we can provide issues for first time contributors. We've found a large audience that would like to contribute to OSS but aren't sure how to navigate the process. We're using this issue (and others in the spring-guides org) largely for educational purposes. Depending on the interest we may look at using an automated workflow in the future.

I will close this issue as the PR is merged. There will likely be new opportunities to upgrade the Boot version in the future.
