Upgrade to RuboCop 1.57.2 which drops base64

[bb]

Please upgrade standard to RuboCop 1.57.2. This version dropped the dependency on the base64 gem.

Earlier versions of RuboCop required base64 version 0.1.x which already caused issues before: rubocop/rubocop#12310

A few hours ago, v0.2.0 was released and automatically loaded with new installations, thus breaking (old) RuboCop again:

 The application encountered the following error: You have already activated base64 0.2.0, but your Gemfile requires base64 0.1.1. Prepending `bundle exec` to your command may solve this. (Gem::LoadError)
