Run bin/rails g annotate_rb:install

Adds a rake task into your Rails project's lib/tasks directory that will
hook into the Rails project rake tasks, automatically running AnnotateRb
after database migration rake tasks.

To skip the automatic annotation that happens after a db task, pass the
environment variable ANNOTATERB_SKIP_ON_DB_TASKS=1 before your command.

$ ANNOTATERB_SKIP_ON_DB_TASKS=1 bin/rails db:migrate
