NoClassDefFoundError: okhttp3/MediaType, after upgrading to 0.18.0

From 0.17.1 onwards the okhttp version was changed to 5.x again and the same issue NoClassDefFoundError came up again, so I had to manually exclude okhttp and import the 4.x version of okhttp.
Or change version to 0.17.0

    <dependency>
        <groupId>com.meilisearch.sdk</groupId>
        <artifactId>meilisearch-java</artifactId>
        <version>0.18.0</version>
        <exclusions>
            <exclusion>
                <groupId>com.squareup.okhttp3</groupId>
                <artifactId>okhttp</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>com.squareup.okhttp3</groupId>
        <artifactId>okhttp</artifactId>
        <version>4.12.0</version>
    </dependency>

Start by reproducing the NoClassDefFoundError with com.meilisearch.sdk:meilisearch-java:0.18.0 and inspect its resolved okhttp dependency, comparing it with 0.17.0 and the reported okhttp 4.12.0 workaround. Done means a normal 0.18.0 dependency can run without manually excluding okhttp or adding a replacement version.
