Consolidate SpringBoot Versions & Fix Release Pipeline

[cicoyle]

• Proper Maven inheritance is utilized

• No redundant configurations in child POMs. Child POMs automatically inherit this property from the parent POM according to the docs here.

• Consistent versioning across modules

• Example modules are properly skipped during deployment

• Fix the nexus staging error in the Publish step here by adding <maven.deploy.skip>true</maven.deploy.skip> to the properties section of the spring-boot-examples parent POM:

• Fix springboot version warning by adding the pluginManagement section to the spring-boot-examples parent POM:

Warning:  
Warning:  Some problems were encountered while building the effective model for io.dapr:producer-app:jar:0.14.0-rc-3
Warning:  'build.plugins.plugin.version' for org.springframework.boot:spring-boot-maven-plugin is missing. @ line 79, column 15
Warning:  
Warning:  Some problems were encountered while building the effective model for io.dapr:consumer-app:jar:0.14.0-rc-3
Warning:  'dependencies.dependency.(groupId:artifactId:type:classifier)' must be unique: io.dapr.spring:dapr-spring-boot-starter:jar -> version ${dapr-java-sdk.alpha-version} vs ${dapr.sdk.alpha.version} @ line 46, column 17
Warning:  'build.plugins.plugin.version' for org.springframework.boot:spring-boot-maven-plugin is missing. @ line 92, column 15
Warning:  
Warning:  It is highly recommended to fix these problems because they threaten the stability of your build.
Warning:  
Warning:  For this reason, future Maven versions might no longer support building such malformed projects.

@cicoyle what about this one? the Maven Site Plugin It think it generates a site for the project. We might need to skip this for both.

@cicoyle This looks good to me.. let's try against maven central.. that is the only way to check
