Code Modernization: Allow some parameters with reserved keywords in `…

…wp-includes/class-wp-text-diff-renderer-*.php`.

This commit adds inline comments instructing PHPCS to ignore parameters with reserved keywords in the affected methods that should not be renamed:
* `$string` parameter in `WP_Text_Diff_Renderer_inline::_splitOnWords()`
* `$final` parameter in `WP_Text_Diff_Renderer_Table::_changed()` and `::interleave_changed_lines()`

This resolves a few WPCS warnings along the lines of:
{{{
It is recommended not to use reserved keyword "string" as function parameter name. Found: $string
It is recommended not to use reserved keyword "final" as function parameter name. Found: $final
}}}

The two `WP_Text_Diff_Renderer_*` classes in question extend the `Text_Diff_Renderer_inline` and `Text_Diff_Renderer` classes from the `Text_Diff` package and should have the same parameters as the parent class methods, per the Task 1 section of ticket #51553.

The `Text_Diff` library currently included in WordPress core is no longer kept in sync with the upstream project and can be considered “adopted”, so the `$string` and `$final` parameters in the  parent class methods can technically be renamed, e.g. to `$input_string` and `$modified`, respectively.

However, the “final” wording is also used to represent modified content in other parts the library, so it is more internally consistent to keep these parameters as is for now.

Follow-up to [7747], [38352], [55136].

See #56788.
