Clarify Required Cloudflare API Token Permissions in SST Documentation

[prabal-rje]

Issue

When integrating Cloudflare with SST as a beginner, it's unclear which permissions are needed for the Cloudflare API token. The documentation doesn't specify the necessary permissions, unlike the detailed guidance provided for AWS credentials. Additionally, using an 'Account' API token instead of a 'User' API token causes silent failures (HTTP 500 errors) when deploying Cloudflare Workers.

Suggestion

• Update Documentation:
  • Specify the exact permissions required for the Cloudflare API token.
  • Clarify the difference between 'User' and 'Account' API tokens and their impact on deployments.
  • Provide step-by-step instructions similar to the AWS credentials guide.

Cheers,
