Backup Documentation seems not up to date

[Schoumi]

Hi,

The Backup sections (https://doc.wallabag.org/en/admin/backup) seems not really up to date. In the Pictures sections, it says that images storage should have change in version 2.2. Since we are at release 2.6.9. I think it has changed.

Maybe take a look to that section and update it if needed will be great :)
I know maintain documentation through time is hard.

Thank you for your work.

Hey, it seems nothing changed yet :)
Images are still saved in the same place:

wallabag/app/config/services.yml

Lines 259 to 261 in 637d8d3

	Wallabag\Helper\DownloadImages:
	arguments:
	$baseFolder: "%kernel.project_dir%/web/assets/images"
