feat: migrate away from deprecated graal-sdk dependency to use nativeimage (#2706)

Merge after googleapis/java-shared-config#815 is
released and updated in sdk-platform-java.


According to the [graal/sdk
CHANGELOG](https://github.com/oracle/graal/blob/fefc2a03a1e46ce60ce4b03f223d83640fbef0f4/sdk/CHANGELOG.md#version-2310),
the GraalVM SDK was split into smaller modules and the use of graal-sdk
is deprecated. The new maven configuration to customize native image
generation is:
```
<dependency>
  <groupId>org.graalvm.sdk</groupId>
  <artifactId>nativeimage</artifactId>
  <version>${graalvm.version}</version>
</dependency>
```
