msggen: Add two missing fields to the listpays schema

The fields were missing because they weren't annotated with a type and
a description. Adding those fixes them.

Changelog-Fixed: msggen: `listpays` now includes the missing `amount_msat` and `amount_sent_msat` fields
No-schema-diff-check: fields were always there, just undocumented!
