There are issue with Dockerfile

Description of problem

Thanks all contributors, this project help me quickly removes labels from docker images.
but I meet some problem when I building Dockerfile:
Error installing fpm
The last version of public_suffix (< 6.0, >= 2.0.2) to support your Ruby & RubyGems was 4.0.7.
Try installing it with gem install public_suffix -v 4.0.7 and then running the current command again.

Question: setting creation date

Hi,
is there a possibility to set the creation date for the newly created image? Or at least keep the original one?
