Timeout stack create at BootstrapWaitCondition

[Anorlondo448]

A timeout occurs when building the cloud9 environment.
https://catalog.us-east-1.prod.workshops.aws/workshops/31676d37-bbe9-4992-9cd1-ceae13c5116c/en-US/installation/setup-cloud9#setup-cloud9-environment

curl -O https://raw.githubusercontent.com/aws-samples/one-observability-demo/main/cloud9-cfn.yaml
aws cloudformation create-stack --stack-name C9-Observability-Workshop --template-body file://cloud9-cfn.yaml --capabilities CAPABILITY_NAMED_IAM

What times out is 'BootstrapWaitCondition' resource.

I tried removing the 'BootstrapWaitCondition' resource from cloud9-cfn.yaml, and it worked.
The 'BootstrapWaitCondition' resource is not being referenced anywhere.
Is this necessary?
