Run `echo 'resource "foo" "%[1]s" {}' | terraform fmt -` ### Additional Context I suspect this may be related to [string directive expressions](https://developer.hashicorp.com/terraform/language/expressions/strings#directives) which are used for evaluating conditionals however, I think `%[...]s` shouldn't be an catching and getting removed here as it is a valid Go template placeholder without an overlap in HCL (at least to my knowledge). ### References _No response_
