Make "vercel dev" work with Ionic Angular projects

[dotNetkow]

When testing Vercel's serverless functions feature locally in an Ionic Angular project, the vercel dev command runs ng serve. The Angular project runs/serves correctly but the API located in the same project does not run at all.

To fix this, the dev command should have --port $PORT appended, just like the Vercel CLI uses for regular Angular projects (Ionic Angular projects are, in fact, just Angular projects).
