IBX-9413: Corrected incorrect type, changed how to retrieve variables

[mateuszdebinski]

🎫 Issue	IBX-9413

get_object_vars - uninitialized properties are considered inaccessible, and thus will not be included in the array.

If we use types for variables they are treated as uninitialized, which is why the get_object_vars function cannot retrieve them. I also don't see the point of assigning null to each variable to initialize it. During the last change, unfortunately, phpVersion was set to string instead of an array, which after fixing the problem with retrieving variables caused a new error

FYI I see that accelerator is indeed visible after your change, but CPU and memory is empty as before. Not sure what determines if the above is available or not.

I tested it on 3 different devices and after the changes, the information about CPU and memory appeared correctly

I tested it locally (Apple M1 Pro) and it failed. 😉 I will let QA give their opinion though...

+1 to unblock QA but this PR doesn't fix the issue on my local machine.

Apple ARM:
CPU NOK
Memory NOK
Accelerator OK

Linux in VM on Apple ARM:
CPU NOK
Memory OK
Accelerator OK

PHP 8.3.14/15/16. Tested on Linux with Apache and Nginx.

Apple Intel:
CPU NOK
Memory NOK
Accelerator OK

Linux in VM on Apple Intel:
CPU OK
Memory OK
Accelerator OK

FWIW, with WSL (Linux on Windows), cpu/mem/acc are all ok before and after the change.

Summary.

On Mac, regardless of architecture, only Accelerator field displays valid value. Reported separately as https://issues.ibexa.co/browse/IBX-9437.

Virtual machines with Linux on Mac:
with Intel - all 3 fields work correctly
with ARM - Memory and Accelerator work, CPU is blank.

On Platform.sh all 3 fields work correctly.
