You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: importmap_generator.rb
    path of file: ./repos/blacklight/lib/generators/blacklight/assets
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Blacklight
  module Assets
    class ImportmapGenerator < Rails::G
    
      def import_javascript_assets
        append_to_file 'config/importmap.rb' do
          <<~CONTENT
            pin "@github/auto-complete-element", to: "https://cdn.skypack.dev/@github/auto-complete-element"
            pin "@popperjs/core", to: "https://ga.jspm.io/npm:@popperjs/core@2.11.6/dist/umd/popper.min.js"
            pin "bootstrap", to: "https://ga.jspm.io/npm:bootstrap@#{(defined?(Bootstrap) && Bootstrap::VERSION) || '5.3.2'}/dist/js/bootstrap.js"
          CONTENT
        end

        append_to_file 'app/assets/config/manifest.js' do
          <<~CONTENT
            //= link blacklight/manifest.js
          CONTENT
        end
      end
