Documentation to disable preview generation wrong

[Kaijudo]

In the documentation, in order to disable preview generation, the config value is set as lazy:

richdocuments/docs/app_settings.md

Lines 40 to 43 in dbaf059

	By default Nextcloud will generate previews of Office files using the Collabora file conversion endpoint. This can be turned off through
	occ config:app:set richdocuments preview_generation --type boolean --lazy --value false

When the configuration value is actually loaded, only non-lazy values are loaded, since getAppValueBool() defaults to non-lazy if not explicitly set.

richdocuments/lib/AppConfig.php

Lines 247 to 249 in dbaf059

	public function isPreviewGenerationEnabled(): bool {
	return $this->appConfig->getAppValueBool('preview_generation', true);
	}
