[Bug] local generate and token

[Amenocy]

Describe the bug

since local docker-based generation, doesn't need Token,

in packages/cli/cli/src/commands/generate/generateAPIWorkspaces.ts , generation type should be checked to throw askToLogin error.
unless you want to force users to work with Github! or give their repo access to Fern in any case!
