Remove unused crate_owner_invitations.token_generated_at column (#10548)

This column has never been used in the 5 years that it existed. The corresponding `CrateOwnerInvitation` model struct even called it `token_created_at` instead of `token_generated_at`, so it couldn't have been used even if the field was accessed...
