CAMEL-23863: Fix invalid YAML in rest-api example

[ammachado]

Motivation

The rest-api example's rest-api.camel.yaml nests the GET verbs under an unsupported steps: key:

- rest:
    path: /api
    steps:
      - get:
          path: /hello
      - get:
          path: "/hello/{name}"

The Camel YAML DSL has no steps: child under rest:; verbs belong directly under get:/post:/etc. As a result the example fails at parse time (UnsupportedFieldException) and camel run --example=rest-api does not start.

Fix

Use the proper get: verb list with explicit to: targets wiring each verb to its direct route, matching the canonical Camel YAML rest DSL structure:

- rest:
    path: /api
    get:
      - path: /hello
        to:
          uri: direct:hello
      - path: "/hello/{name}"
        to:
          uri: direct:hello-name

The two direct:hello / direct:hello-name routes already present in the file remain unchanged.

Related

This is the upstream source for the bundled example that is synced into apache/camel via the sync-example-catalog Maven profile. The same fix has been applied on the camel side, together with a new ExampleRoutesLoadTest that loads and parses every bundled example through the routes loader to prevent this class of regression:

• CAMEL-23863: Fix invalid YAML in rest-api jbang example and add example-loading test camel#24340

Without this upstream change, the next example-catalog sync would re-introduce the broken file.
