Consistently use quarkus-generator.openApiSpecId as openApiSpecId in templates (#848)

as otherwise using the `configKey` instead can lead to a mismatch and an exception like:

```
[error]: Build step io.quarkus.arc.deployment.ArcProcessor#validate threw an exception: jakarta.enterprise.inject.spi.DeploymentException: jakarta.enterprise.inject.UnsatisfiedResolutionException: Unsatisfied dependency for type io.quarkiverse.openapi.generator.providers.CompositeAuthenticationProvider and qualifiers [@OpenAPISpec(openApiSpecId = "your-config-key-not-the-same-as-spec-id")]
        - injection target: parameter 'compositeProvider' of com.acme.api.auth.AuthenticationPropagationHeadersFactory constructor
        - declared on CLASS bean [types=[com.acme.api.auth.AuthenticationPropagationHeadersFactory, io.quarkiverse.openapi.generator.providers.AbstractAuthenticationPropagationHeadersFactory, org.eclipse.microprofile.rest.client.ext.ClientHeadersFactory, java.lang.Object], qualifiers=[@default, @Any], target=com.acme.api.auth.AuthenticationPropagationHeadersFactory]
        The following beans match by type, but none has matching qualifiers:
        - SYNTHETIC bean [types=[io.quarkiverse.openapi.generator.providers.CompositeAuthenticationProvider, java.lang.Object], qualifiers=[@Any, @io.quarkiverse.openapi.generator.OpenApiSpec(openApiSpecId = "your-spec-id-not-the-same-as-config-key")], target=n/a]
