Release script plain ruby fixes

[Naragod]

Proposed Changes 🐛 Bug fix

The release/* scripts crash when run outside Rails. This PR converts them to plain Ruby so they run, and exempts release/ from rubocop check to prevent reintroducing the crash.

The scripts run as standalone ruby. The cherry-pick loop and the release playbook invoke them without Rails. They call ActiveSupport methods that load with Rails:

• pluck / index_by
• present?
• Time.zone.parse
• String#exclude?

Under plain ruby, each raises NoMethodError. Master's recon.rb dies with undefined method 'present?' for an instance of String. Rubocop masks this. The repo runs rubocop-rails, whose cops prefer those methods. Rails/Pluck demands pluck. Rails/NegateInclude demands .exclude?. The scripts pass lint and crash at runtime.
