deps: Update gRPC-Java to v1.82.2 (#13877)

Result of running `librarian generate --all`.

This may also contain changes regenerated from googleapis proto changes.
Might have been from the `go run
github.com/googleapis/librarian/cmd/librarian@${V} update
sources.googleapis` command while following the playbook, but was
running into librarian generation issues so I follow the steps to setup
librarian first.

Not sure how to "un-update the sources" from a local librarian install,
but I don't think this generation should have an harm as it should have
the updated sources.
