Task/Development/Changelog documentation still references removed method askForChanges

[filliph]

Steps to reproduce

$this->taskChangelog()
	->version($version)
	->askForChanges()
	->run();

As per the documentation: https://robo.li/tasks/Development/

Expected behavior

I expect to be asked for the changelog entries via the console.

Actual behavior

ERROR: call_user_func_array() expects parameter 1 to be a valid callback, class 'Robo\Task\Development\Changelog' does not have a method 'askForChanges' 
in phar:///usr/local/bin/robo/src/Collection/CollectionBuilder.php:399

System Configuration

macOS 10.13.5, PHP 7.1.18

Will the documentation ever be fixed? It's been almost two years and this issue is still not resolved.
