doc: fix `added:` date for `NODE_REPL_HISTORY`
NODE_REPL_HISTORY
was introduced in v3.0.0 (see e.g. 6faf17cb).
I noticed this while doing the conflict resolution for the backport in #7677, and I think I wanted to PR that against master right then, but ended up correcting the version in the backport – sorry for that.
