Update parent pom.xml to exclude junit-vintage-engine

[akashsolanki]

This change introduced spring-boot-starter-test dependency but it did not exclude junit-vintage-engine which is causing issues when running junits independently.

Below dependency should be changed from -

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <version>${spring-boot.version}</version>
                <scope>test</scope>
                <exclusions>
                    <exclusion>
                    <groupId>junit</groupId>
                    <artifactId>junit</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>

to

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <version>${spring-boot.version}</version>
                <scope>test</scope>
                <exclusions>
			        <exclusion>
			            <groupId>org.junit.vintage</groupId>
			            <artifactId>junit-vintage-engine</artifactId>
			        </exclusion>
			    </exclusions>
            </dependency>
