Enhancement

Advertise Bundler & Hanami installation while running hanami new

⚡ hanami new bookshelf
-> Within bookshelf/
⚡ hanami new bookshelf
Created bookshelf/
-> Within bookshelf/
Created .env
Created README.md
Created Gemfile
Created Rakefile
Created config.ru
Created config/app.rb
Created config/settings.rb
Created config/routes.rb
Created config/puma.rb
Created lib/tasks/.keep
Created lib/bookshelf/types.rb
Created app/actions/.keep
Created app/action.rb
Running Bundler install...
Running Hanami install...

👉 The last two lines are the addition of this enhancement.

Why?

Bundler, and potentially Hanami, installation can be time consuming.

Without advertising their execution, the user has the impression that hanami new is stuck at the last file creation (e.g. Created app/action.rb).
