Updating only tags for `AWS::AppRunner::Service` causes panic

[connec]

Low priority since CloudFormation itself fails on tag-only updates to AWS::AppRunner::Service. The panic originates here:

cloudformatious/src/change_set.rs

Lines 666 to 677 in 73cf5ae

	assert!(
	// We assume that changes to these attributes would never require recreation.
	// NOTE: CloudFormation may report tag changes on AWS::SecretsManager::Secret
	// resources as conditionally requiring recreation. We assume this is a bug in
	// CloudFormation and ignore it.
	matches!(
	target.requires_recreation,
	None | Some(aws_sdk_cloudformation::model::RequiresRecreation::Never)
	) || resource_type == "AWS::SecretsManager::Secret",
	"ResourceTargetDefinition with attribute {:?} with requires_recreation",
	attribute
	);

Note that there's already an exception for AWS::SecretsManager::Secret (introduced in 7e5e35d). For now we could simply add an additional exception for AWS::AppRunner::Service.
