[Typo] First Time AWS Cloudformation Stack Creation by User

[sn0wcr0w]

Small problem:
https://github.com/elastic/detection-rules/blob/main/rules/integrations/aws/execution_new_terms_cloudformation_createstack.toml

The text on line 10 should read AWS Cloudformation, not AWS Cloudwatch

This has been addressed as part of the most recent rule tuning for this rule. The updated version will be available in our next Detection Rules release, thank you for submitting the issue @sn0wcr0w
