This modifies a handful of commands to better integrate with Thor's help
system.

__Before (examples)__

  ```console
  $ bin/rails dbconsole --help
  Usage:
    bin/rails dbconsole

  Options:
    -e, [--environment=ENVIRONMENT]                    # The environment to run `dbconsole` in (e.g. test / development / production).
    -p, [--include-password], [--no-include-password]  # Automatically provide the password from database.yml
        [--mode=MODE]                                  # Automatically put the sqlite3 database in the specified mode (html, list, line, column).
                                                       # Possible values: html, list, line, column
        [--header], [--no-header]
    --db, [--database=DATABASE]                        # Specifies the database to use.

  $ bin/rails server --help
  Usage:
    bin/rails server -u [thin/puma/webrick] [options]

  Options:
    -e, [--environment=ENVIRONMENT]              # The environment to run `server` in (e.g. test / development / production).
    -p, [--port=port]                            # Runs Rails on the specified port - defaults to 3000.
    -b, [--binding=IP]                           # Binds Rails to the specified IP - defaults to 'localhost' in development and '0.0.0.0' in other environments'.
    -c, [--config=file]                          # Uses a custom rackup configuration.
                                                 # Default: config.ru
    -d, [--daemon], [--no-daemon]                # Runs server as a Daemon.
    -u, [--using=name]                           # Specifies the Rack server used to run the application (thin/puma/webrick).
    -P, [--pid=PID]                              # Specifies the PID file - defaults to tmp/pids/server.pid.
    -C, [--dev-caching], [--no-dev-caching]      # Specifies whether to perform caching in development.
        [--early-hints], [--no-early-hints]      # Enables HTTP/2 early hints.
        [--log-to-stdout], [--no-log-to-stdout]  # Whether to log to stdout. Enabled by default in development when not daemonized.
