grpc-bom dependency doesn't properly generate in pom.xml

This was discussed in https://wiremock-community.slack.com/archives/C03NAEH5LVA/p1698103015215289

As it stands today, the grpc-bom artifact in the resulting pom.xml is declared as a jar dependency in the <dependencies> section, rather than a pom import dependency within the <dependencyManagement> section of pom.xml.

This causes clients using Maven to fail when using this library:

If adding this to pom.xml:

<dependency>
  <groupId>org.wiremock</groupId>
  <artifactId>wiremock-grpc-extension</artifactId>
  <version>0.2.0</version>
  <scope>test</scope>
</dependency>

it results in:

./gradlew clean check still is successful and a maven client is able to pull the dependency properly after this change.
