Set Node version in a single place (#6534)

This should make it much easier to update.  Also use 18.15.0
specifically since that is what VS Code ships with.

Additionally, it fixes the post-install script being skipped due to
a Yarn v1 bug that happens when Yarn installs node-gyp, which
it does because 18.18 onward stopped bundling node-gyp.
