Update Node version to 18.x

[hasanabuzayed]

Workflow action started failing after danger-js dropped support for node older than 18.

This is the error I've been getting and from what I've seen this started when danger-js@12.0.1 was released.

@f-meloni could you please take a look at this whenever you get the chance? thanks!

@f-meloni could you "push the button" on a release for this one? Currently it's required for any gihub step out there to run

Sorry I needed to use my Mac, so I had to wait to be at home. Done! :)
