Checklist

• I've run bundle exec rspec from the root directory to see all new and existing tests pass
• I've followed the fastlane code style and run bundle exec rubocop -a to ensure the code style is valid
• I've read the Contribution Guidelines
• I've updated the documentation if necessary.

Motivation and Context

Implements #19581

Description

Added "configuration" option to the pod_lib_lint action. This maps to the "--configuration" option that is available in CocoaPods since v1.10.

Testing Steps

Apart from added unit tests, I've tested the setup locally with a pod I maintain and the lane like:

  lane :test_fastlane_change do
    pod_lib_lint(
      podspec: "POD_NAME.podspec",
      allow_warnings: true,
      skip_tests: true,
      platforms: "macos",
      no_subspecs: true,
      configuration: 'Debug'
    )
  end
