Code Modernization: Fix reserved keyword and parameter name mismatches for parent/child classes in `Walker::start_el()`. 

In the parent class, renames the parameter `$object` to `$data_object`.

Why? `object` is a PHP reserved keyword.

In each child class: renames the corresponding parameter to match the parent's method signature.

Why? 

PHP 8 introduces the ability to pass named arguments to function/method calls. This means the child and parent method signatures (i.e. parameter names) need to match.

Changes for readability:

- `@since` clearly specifies the original parameter name and its new name as well as why the change happened.

- in methods longer than a single line, the generic parameter is reassigned to the original parameter restoring it for context for use within the method. An inline comment is added to explain why this reassignment is made.

- in cases where the original parameter name was too generic, renamed (when reassigning) to a more descriptive name for use within the method.

Follow-up to [7737], [8900], [8970], [14248], [15077], [16100], [25642], [25644], [37051], [37054], [37056], [46271], [47189].
