Is there an existing issue for this?
Which topic?
https://developer.adobe.com/commerce/php/best-practices/phpstorm/install/
What's wrong with the content?
The content has not been updated to warn users that the plugin does not work with the new version of PHPStorm, 2024.1.4 at the time of writing, as it can be seen on the official page: https://plugins.jetbrains.com/plugin/8024-magento-phpstorm

What changes do you propose?
The content should be updated with a new plugin version or workarounds on what to do to make it work with new releases of PHPStorm
Anything else that can help to cover this?
The documentation team should contact the plugin's developer and ask them to update it, or provide an alternative. Otherwise, if it is discontinued, then the relevant content should be discontinued as well.
