kotlin-stdlib version conflicts downstream

[andykruth-ii]

Including some dependencies downstream cause a 1.2.X version of kotlin-stdlib and a 1.3.X version of kotlin-stdlib-common to be pulled in which causes version clash issues at runtime (NoSuchMethodError's).

Ex.

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-dependencies</artifactId>
            <version>2.1.1.RELEASE</version>
            <scope>import</scope>
            <type>pom</type>
        </dependency>
        <dependency>
            <groupId>com.expediagroup.streamplatform</groupId>
            <artifactId>stream-registry-state-graphql-sender</artifactId>
            <version>0.16.0</version>
        </dependency>
    </dependencies>
</dependencyManagement>

<dependencies>
    <dependency>
        <groupId>com.expediagroup.streamplatform</groupId>
        <artifactId>stream-registry-state-graphql-sender</artifactId>
    </dependency>
</dependencies>

This resolves to:

• kotlin-stdlib : 1.2.71
• kotlin-stdlib-common : 1.3.72

Proposed solution is to solidify kotlin-stdlib and kotlin-stdlib-common dependency versions in graphql-sender. Can also take this opportunity to update the kotlin-stdlib dependency in the top level pom.
