[Content]: Coding guideline examples incorrect

Description

The coding guidelines have examples which don't work, and, never have:

https://craftcms.com/docs/5.x/extend/coding-guidelines.html

For example:

Use those instead of their magic properties:

// Bad:
\Craft::$app->entries->saveEntry($entry);

// Better:
\Craft::$app->getEntries()->saveEntry($entry);

Neither of these lines of code work in Craft 3, 4 or 5, where they are shown.

The correct code should be:

Craft::$app->getElements()->saveElement($entry);

I believe this was corrupted when rewritten from Craft 2:

craft()->entries->saveEntry($entry);
