Change ActiveRecord::Migration to ActiveRecord::Migration[7.1]

[lenikadali]

• Changed the line ActiveRecord::Migration to ActiveRecord::Migration[7.1] so that schema loading could work (it is now required for newer versions of Rails)
• Updated and commented out the load schema task since it fails to find and run the loading of data into the database PostgreSQL container
• Added the initialize_profile method and add it to the after_create portion of the User factory because of the NameError I encountered:
• NameError: undefined local variable or method `init_profile' for #FactoryBot::SyntaxRunner:0x00007eaac2e3c560 (NameError)
