Prevention of the warning caused by an access to an undefined property (php8)

[pospjan]

Access to an undefined property was a notice in php 7.4, but was changed to a warning in php 8. And as the Adminer is "hiding" only notices, this warning has started to appear while submitting custom queries:

I'm facing this issue as well. A good alternative I've used in the mean time is to run this in the console (CTRL+SHIFT+I) to remove those warnings in the table headers.

var children = document.querySelectorAll('th');
for(var i = 0; i < children.length; i++){
var newText = children[i].innerHTML.replace(<br> <b>Warning</b>: Undefined property: stdClass::$type in <b>/var/www/html/adminer.php</b> on line <b>1484</b><br>,'');
children[i].innerHTML = newText;
}

I'm using the tilda (`) to find the string properly, but it's the same syntax as the code indicator in here.

I found out that this problem is better (more universally) solved in #429

So close this PR and let's get #429 merged please
