ferric-example: update napi-rs crates and drop napi-sys pin

Bump napi to 3.14.2, napi-derive to 3.6.12 and napi-build to 2.6.0,
and remove the direct napi-sys =3.0.1 pin added for #331.

napi now depends on napi-sys with default-features = false and only
enables its dyn-symbols feature through napi's own default features,
which this crate already disables. The addon therefore links the
Node-API symbols at link time (resolved by weak-node-api) rather than
loading them from the host process.
