Serverless Stack

Getting
```
ERROR: Failed to run: CDK_DISABLE_VERSION_CHECK=true SEED_UPDATE_CDK_ASSETS=.build/cdk.out cdk deploy --app .build/cdk.out --all --require-approval never --no-color --verbose```
When trying to deploy to `ap-southeast-2`
Any ideas?

`
``` Error: This stack uses assets, so the toolkit stack must be deployed to the environment (Run "cdk bootstrap aws://*********/ap-southeast-2")```


`npx cdk bootstrap <aws://631303892699/ap-southeast-2>`

Would be nice if Seed ran this command if it got the above error :thumbsup:

Hey <@U0205U47LJU> actually SST should auto-bootstrap. This might be a corner case we are handling. To clarify:
1. Was this account/region never been bootstrapped before?
2. What version of SST r u using?
