Changes

Bump version: 1.12.0.23-dc62-dirty → 1.13.0

This release was made on top of commit 6213201b ("ranap: Reject
ActivatePDPCtx from UE if RABAssResp parsing fails") instead of master
as master is currently too much in WIP state for making a release, as
discussed with Alexander and Pau. The release also has several fixes
from master backported.
