[IAM Credentials Migration] [Code build & CR package] Update the codebuild spec to use the IAM role created to replace the credentials from secret manager

Update the codebuild spec to use the IAM role created to replace "packages-e2e". Look for the packages_ci_beta:aws_access_key_id and packages_ci_beta:aws_secret_access_key_id

Update the codebuild spec to use the IAM role created to replace "non-regional-packages-e2e". Look for the packages_ci_beta:non_regional_aws_access_key_id and packages_ci_beta:non_regional_aws_secret_access_key_id

Update the codebuild spec to use the IAM role created to replace "cert-manager-e2e". Look for the packages_ci_beta:route53_access_key_id and packages_ci_beta:route53_secret_access_key

Refer to
https://repost.aws/knowledge-center/codebuild-temporary-credentials-docker for details on how to use the credentials from IAM role

Locate the CodeBuild specification and search for packages_ci_beta:aws_access_key_id, packages_ci_beta:non_regional_aws_access_key_id, and packages_ci_beta:route53_access_key_id, along with their secret counterparts. Read the referenced AWS guidance on temporary credentials for Docker. Done means all three credential pairs are replaced with the corresponding IAM roles without retaining the Secret Manager credentials.
