Fix method name missing in spring-plugins:scheduled-annotation-plugin with spring 6.1.x

• Add a unit test to verify that the fix works.
• Explain briefly why the bug exists and how to fix it.

Since Spring 6.1.x, the intercepted method deprecated

  @Deprecated(
        since = "6.1"
    )
    @Nullable
    protected Runnable createRunnable(Object target, Method method) {
        return null;
    }

use the constructor method instead:

  public ScheduledMethodRunnable(Object target, Method method, @Nullable String qualifier, Supplier<ObservationRegistry> observationRegistrySupplier) {
        this.target = target;
        this.method = method;
        this.qualifier = qualifier;
        this.observationRegistrySupplier = observationRegistrySupplier;
    }

Before adjustment:

Are we sending too frequently? The test GHA env is only 3u8g for all runtime. It could be super slow.
