Change suffixes produced by `TKit.createUniqueFileName()` function from `.<NUM>` to `-<NUM>` (e.g.: from `.0` to `-0`). Apple's `codesign` tool can't sign directories with periods in their names as it interprets them as bundles. Directories produced by `TKit.createUniqueFileName()` may end up in an app image and become a subject for signing if used with `--app-content` jpackage parameter
