Review comment:
       I believe that this is technically more performant as it does not generate three strings like the previous version, which generated `"Failed to delete: "`, the string for `file` and then another string for the final result (without using StringBuilder).
   
   This case should generate one less string at runtime: the `file` string and the templated `Failed to delete: $file`. Additionally, I believe the use of the format string is lazily evaluated (so the string won't be created if the exception is not thrown), but I might be mistaken on that part.
   
   Probably the tldr is that it's better because the linting automation enforces it currently and thus it brings standardization to the code base.
