If you need the older version I would get a CVS checkout of the
OPENBSD_7_7 ports tree (see the faq), then

cd /usr/ports/lang
cp -r node node20
cd node20
cvs up -r OPENBSD_7_6 -Pd
make prepare FETCH_PACKAGES=
make package

(or e.g. "make package MAKE_JOBS=4" to use multiple cores to speed up
the build)

this is not "supported" but will likely work with no or minimal changes
to the port.
