is there any difference in maven dependency for Netflix zuul and ribbon while upgrading to Spring boot 2.5.1 and spring cloud 2020.0.3

Question

I am trying to upgrade my spring boot version from 2.1.5.RELEASE to 2.5.1, so I have changed the spring cloud version from Greenwich.RELEASE to 2020.0.3 according to release train Spring Boot compatibility for spring cloud. I am also using spring-cloud-starter-netflix-zuul and spring-cloud-starter-netflix-ribbon in my project. The issue I am facing is when I build the maven, I'm getting error as follows

[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[ERROR] 'dependencies.dependency.version' for org.springframework.cloud:spring-cloud-starter-netflix-zuul:jar is missing. @ com.xx.xxx.xxx:[unknown-version], C:\Users\xx\pom.xml, line xx, column xx
[ERROR] 'dependencies.dependency.version' for org.springframework.cloud:spring-cloud-starter-netflix-ribbon:jar is missing. @ com.xx.xxx.xxxh:[unknown-version], C:\Users\xx\pom.xml, line xx, column xx

My pom file is as follows

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.5.1</version>
    </parent>
    <repositories>
    </repositories>

                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>

        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
        </dependency>

Numerous Netflix-related modules that were previously in maintenance mode have been removed in Spring Cloud 2020. This includes Ribbon and Zuul which you are using. The Spring Cloud team recommend replacing Ribbon with Spring Cloud Loadbalancer and Zuul with Spring Cloud Gateway.

Spring removed zuul after 2.4.0 so it better to use below versions for smooth excution.

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.3.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>

<properties>
    <java.version>1.8</java.version>
    <spring-cloud.version>Greenwich.RELEASE</spring-cloud.version>
</properties>


<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
    </dependency>
