Adds known issue for aarch64 pwd generation (#83654)

We figured out that on Linux and macOS aarch64, we can't
determine whether a terminal is attached to elasticsearch and as
such we don't print the elastic password and enrollment token on
node first startup. This is resolved in #83566 by updating the
underlying library we use to detect the terminal.
