Function _load_textdomain_just_in_time was called incorrectly

[threadi]

Using the plugin with WordPress 6.7 results with enable debug-mode in this message:

Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the health-check domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see [Debugging in WordPress](https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/) for more information. (This message was added in version 6.7.0.) in /var/www/clients/client1/web3/web/wp-includes/functions.php on line 6114

Reason should be the loading of translatable text here: https://github.com/WordPress/health-check/blob/trunk/HealthCheck/Tools/class-health-check-files-integrity.php#L20 but also in multiple other files without any surrounding hook.

Meanwhile, I created a simple mu-plugin to remove all these notice messages. Turns out, there are many other plugins with the same issue.

Just drop-in in your wp-content/mu-plugins directory.
