Immutable annotation?

Hi 👋
We're in the process of migrating off javax to jakarta annotations and we were wondering what the alternative to `javax.annotation.concurrent.Immutable` would be?
It doesn't seem to be present in this repo, would this be an oversight or is there a specific reason?
Thanks for the help!

Start by reviewing the Jakarta Annotations API scope and comparing it with javax.annotation.concurrent.Immutable. Determine whether this repository should provide an alternative or whether the annotation belongs elsewhere; done means documenting a maintainer-confirmed answer for Jakarta migration users.
