Keep the codestart Gradle wrapper in sync with version configured

[gsmet]

This is a follow-up of #48395 and it should be more future-proof and also easier to backport.

@ia3andy I have a question for you: in devtools/project-core-extension-codestarts, we also include a Gradle wrapper in the gradle-wrapper/ directory of the jar. Do you know if this is actually used or if we should drop this? I see commits in there from time to time to fix things but I don't understand why we would have two copies of the wrapper. Or is it to support older projects?
