Fixing integer usage in ownership doc
Fixing integer usage in ownership doc

`int` doesn't exist anymore. Usage of its equivalent `isize` is
discouraged since its size is platform-dependent. `i32` is used instead
in the examples. Also, integer suffixes aren't needed in the examples
anymore so we can just write `5` instead of `5i`.
