[DOC] Tweak the doc for Process.kill signature

Browse source 
Replacing `...` with `*pids` seems to clarify the expected variadic arguments.

Note that the expected arguments are two or more with a signal and pids.
That is, the method must have at least one pid, which cannot be omitted:

```console
% ruby -e 'Process.kill(0)'
-e:1:in `kill': wrong number of arguments (given 1, expected 2+) (ArgumentError)
        from -e:1:in `<main>'
```
