Issues with passing VERCEL_TOKEN as Env var

Add support for VERCEL_TOKEN environment variable by TooTallNate · Pull Request #14831 · vercel/vercel · GitHub added support for the VERCEL_TOKEN environment variable, but there seems to be a bug in the implementation.

Problem

The VERCEL_TOKEN environment variable is being read after the missing-token error is already thrown in non-TTY environments. This causes CI pipelines with VERCEL_TOKEN set to fail unnecessarily.
