Bump PHP version to 8.5

[celyes]

Description

Bump the PHP version and the used packages to 8.5 and the compatible versions

Motivation and context

Using PHP 7.2 is problematic since the support for it has already ended. More about it here

Note on scrutinizer.yml: Removed unsupported keys like fix_identation_4spaces and other fix_* settings that aren’t supported anymore. Scrutinizer no longer configures coding-style fixes directly in the checks.php block. More about it here
