Provide a description of the task

$ nvm install node
npm ERR! `spin` is not a valid npm option

The command "npm config set spin false" failed and exited with 1 during .

I propose to use the latest LTS instead of any latest Node version.

Done. See the reference commits above.

I noticed that CI (example run) started reporting the same error again:

npm ERR! `spin` is not a valid npm option
npm ERR! A complete log of this run can be found in:

$ node --version
v18.14.0

$ npm --version
9.3.1

$ nvm --version
0.39.3

It turns out that the minor bump of Node from v18.13.0 to v18.14.0 made a major bump of npm from 8.19.3 to 9.3.1.

Previously, npm was throwing an error that ended the CI run. Now, in version 9.3.1, npm probably doesn't throw an error anymore, so CI is not stopped.
