[GraalVM for JDK 26] Handle new warnings count message

[jerboaa]

In recent CI runs we see a couple of Mandrel IT tests failing with:

It affects GraalVM for JDK 26 community builds as well as mandrel.

It looks like oracle/graal#12162 introduced a new change with additional warnings count prints such as:

Warning: Option 'DynamicProxyConfigurationResources' is deprecated and might be removed in a future release: This can be caused by a proxy-config.json file in your META-INF directory. Consider including proxy configuration in the reflection section of reachability-metadata.json instead.. Please refer to the GraalVM release notes.

For helidon we have this:

We need to adjust this due to the recent graal/master changes. Tracked in #369
