[Grpc] Add a golden snapshot for the gRPC routing data generator (#58)

# Description

`GoldenSnapshotTest` pins the full emitted source for four of Sindri's
five Ast
data-file generators — container, event, HTTP and CLI routing. The
fifth,
`AstGrpcDataFileGenerator` (added in #38), has only substring assertions
in
`AstGrpcDataFileGeneratorTest`, so a change to the generated shape — the
header
comment, the package line, the imports, the record declaration, the
`Map.of`
wrapping — would pass unnoticed for gRPC while being caught for every
other
protocol.

gRPC is Java-only; neither `sindri-php` nor `sindri-ts` has a gRPC
generator, so
there is no sibling port to change alongside this.

The golden was generated with the `GOLDEN_UPDATE=1` switch from #57 and
reviewed
before committing. `./gradlew ci` passes.

## Changes

- **`GoldenSnapshotTest.java`** — added `grpcRoutingDataMatchesGolden`,
driving
`AstGrpcDataFileGenerator` with two fully-qualified gRPC method routes
so the
emitted `routes()` map is multi-entry, matching how the CLI case is
shaped.
- **`golden/AppGrpcRoutingData.golden`** — the committed snapshot,
covering the
  `GrpcRoutingDataContract` imports and the generated record body.
