[workflow] Use LTS node version and split "Run test" step (#3767)

Two small changes to the workflows:

- Run linter and spellcheck workflows with LTS node version. The
advantage of this is that we no longer have to raise the node version
for them.
- Split "Run test" step into two steps for more clarity.
