nodejs 10.19 deb in ubuntu 20.04 doesn't know about tls v1.3 yet

mediawiki 1.34.2 / parsoid 0.11.0all from the mw-repo on ubuntu 20.04, served by apache. apache redirects all non-https-requests to https, with

sslprotocol             all -SSLv3 -TLSv1 -TLSv1.1 -TLSv1.2

in the apache configuration i'm getting an

"Error loading data from server: apierror-visualeditor-docserver-http-error: http-bad-status. Would you like to retry?" error msg when trying to use visualeditor. in the logs:

… removing -TLSv1.2 from the sslprotocol-config causes it to work as expected.

… not really parsoids fault, the nodejs 10.19 deb in ubuntu 20.04 doesn't know about tls v1.3 yet:

root@mediawiki:~# grep -i tlsv1. nodejs-10.19.0~dfsg/lib/_tls_common.js

  if (v === 'TLSv1') return TLS1_VERSION;

  if (v === 'TLSv1.1') return TLS1_1_VERSION;

  if (v === 'TLSv1.2') return TLS1_2_VERSION;
