Subject: cli: remove deprecated V8 flag
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Remove the `--huge-max-old-generation-size` V8 flag from the
`NODE_OPTIONS` allowlist. That flag was recently deprecated (it
currently remains as nop, see crrev.com/c/5831467) and will soon be
completely removed.
