Coding Standards: Rename the $strResponse argument to `$str_respons…

…e` in `WP_Http::processResponse()`.

This fixes a `Variable "$strResponse" is not in valid snake_case format` WPCS warning.

Additionally, rename a `$res` variable to `$response` for clarity.

Follow-up to [8516], [51823], [51826], [51877].

See #53359.
