npm run tests-only command doesn't exist

I've noticed that in the CONTRIBUTING.md it is mentioned to run either npm test or npm run tests-only for testing,
however npm run tests-only command isn't defined.

That's a good point; the text was copy-pasted from other repos, and this is one of the only ones I don't use that pattern on.

Do you think it's worth opening a PR or should I close the issue?

To update the contributing file, yes, that’d be great thanks.
