Hacky intermediate package for Node?

[Christopher Lemmer Webber]

Our Node is out of date, but this may be fine security-wise and
package-needs wise for the moment; see also:

  https://issues.guix.gnu.org/issue/34526

Unfortunately updating it seems difficult for the reasons described in
that package (the Node community introduced more classic bootstrapping
problems).  Unfortunately I have a pressing project which requires a
more recent version of Node; I'm trying to figure out how I can get a
newer version that runs using Guix.  If it does something hacky, I'm ok
with it for now.

I know some other people here use Guix as the distro on which they do
Node development; maybe someone already has a hacky package that can't
quite make it into mainline yet?  I'd love the recipe if you do.
