fix: iOS hermes detection

[pjc0247]

The original regex fails to match RN's default template.

const t = `
require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

platform :ios, '11.0'

target 'HelloWorld' do
  config = use_native_modules!

  use_react_native!(
    :path => config[:reactNativePath],
    # to enable hermes on iOS, change \`false\` to \`true\` and then install pods
    :hermes_enabled => true
  )

  target 'HelloWorldTests' do
    inherit! :complete
    # Pods for testing
  end

  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable the next line.
  use_flipper!()

  post_install do |installer|
    react_native_post_install(installer)
    __apply_Xcode_12_5_M1_post_install_workaround(installer)
  end
end
`;

// old one
console.log(/^([^#\n]*:?hermes_enabled(\s+|\n+)?(=>|:)(\s+|\n+)?true)$/.test(t));

// fixed one
console.log(/([^#\n]*:?hermes_enabled(\s+|\n+)?(=>|:)(\s+|\n+)?true)/.test(t));

Lovely, can this be a beta/alpha release? Currently i pulled the git, build it my self and merged.
This fixed a mayor issue with use together with --use-hermes.
