"The server cannot process the image" error, set_imagick_time_limit() and WP 6.2

[delitestudio]

On many of our sites, managed on different machines and with different configurations, with version 6.2 of WordPress, when uploading images we often get this error:

"The server cannot process the image. This can happen if the server is busy or does not have enough resources to complete the task. Uploading a smaller image may help. Suggested maximum size is 2560 pixels."

Nothing appears in the debug.log, but analyzing the issue -which had never occurred before WordPress 6.2- we realized that it seems to be due to the new set_imagick_time_limit() method of the WP_Image_Editor_Imagick class.

Maybe the value 0.8 * $php_timeout is that a bit too conservative? Maybe it could be made hookable?
