doc bug, downloadMany(), example

[stheine]

Describe the bug

you document

// download body part nr '1.2' from latest message
let response = await client.downloadMany('*', ['2', '3]);

but this seems to be a c&p issue and should rather read

// download the body parts 2 & 3 of the newest message

Thanks. It's a copy-pasta issue. Fixed with 52d72beafef3151e8b3620e732eff66b6fc9706d
