Bump rustnetconf-yang to v0.1.3 (docs clarification, #30)

Documentation-only patch release of the rustnetconf-yang crate. Clarifies
the required `generated` feature flag and the bundled-vs-custom yang-models
distinction. No API or behavior changes; library and CLI crates unchanged.

+- Module docs now state that generated types require enabling the `generated` Cargo feature (off by default) — without it the `ietf_*` modules are absent.
+- Clarified that codegen reads the crate's own bundled `yang-models/`, not the consumer's project; documented how to vendor the crate to use custom YANG files.
+- Corrected the usage example to the real generated API (`Option`-wrapped fields, `type` leaf emitted as `type_`).

 ## What's New in v0.12.0
 
 OpenSSH `known_hosts`-style host-key pinning for fleet operation. Merged via PR #29 (closes #28).
