Fix API key auth

[Quinn-With-Two-Ns]

Fix some issues with API key auth:

• If the worker was not connected the SDK would try to make a health check call which is not namespaced so doesn't work well with API keys
• typo in the spring auto config

connect was already calling getServerCapabilities but then made a gRPC health check call after which is unnecessary and failed with API keys since it didn't have a namespace

With Spring Boot (v1.28.1), for this to work, I have to configure TemporalOptionsCustomizer<WorkflowServiceStubsOptions.Builder> as follows :

    @Bean
    public TemporalOptionsCustomizer<WorkflowServiceStubsOptions.Builder>
    customServiceStubsOptions() {

        return optionsBuilder -> {

            try {
                optionsBuilder.setSslContext(
                        SimpleSslContextBuilder.noKeyOrCertChain().setUseInsecureTrustManager(false).build());
            } catch (SSLException e) {
                throw new RuntimeException(e);
            }

            return optionsBuilder;
        };
    }

To force the use of Java's default Trust Managers. I confess I don't understand why you need to do this (although with Temporal SDK directly I don't need it).

I based this on the configuration used on Quarkus : https://github.com/quarkiverse/quarkus-temporal/blob/6beb65c18520699577eb2682704bb01fc0d81566/extension/runtime/src/main/java/io/quarkiverse/temporal/WorkflowServiceStubsRecorder.java#L88

Without this configuration I have this stacktrace :
