We would like a newer nodejs for gitlab as well. node-yaml 2.x fails 
with

# nodejs -e 'require("yaml")';
/usr/share/nodejs/yaml/dist/compose/composer.js:33
                if (prelude[i + 1]?.[0] !== '#')
                                   ^

SyntaxError: Unexpected token '.'

as a temporary fix, getting node-yaml backports to transpile correctly 
to be run with nodej 12 will also be good (though eventually more and 
more modules are going to need newer nodejs, so an updated nodejs will 
help till we get next stable version).

I tried different babel options but none of them seems to be working 
for optional chaining operator transpiling. I tried target node 12 for 
babel preset env, tried explicitly adding this plugin for optional 
chaining operator etc (by patching config/babel.config.js - adding top 
level preset as well as adding to overrides).
