Gem::LoadError (Specified 'sqlite3' for database adapter, but the gem is not loaded. Add gem 'sqlite3' to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).):

と記載があるので、Gemfileにgem 'sqlite3'を記載、その後、ターミナルで$ bundle installしてみてはいかがでしょうか？

GemfileのSQL3で指定した1.3.13のバージョンのファイルがありませんと記載されています。

Gemfileを
gem 'sqlite3','1.3.13'(1.3.13のバージョン指定)から
gem 'sqlite3'(バージョン指定なし)に変えるとどうでしょうか？
