Maven build issues fixes

[nicolaskrier]

I have addressed the following warnings and errors that occurred during the Maven build:

[WARNING] 
[WARNING] Some problems were encountered while building the effective model for org.springframework.ai:spring-ai-docs:jar:1.0.0-SNAPSHOT
[WARNING] 'build.plugins.plugin.version' for io.spring.maven.antora:antora-component-version-maven-plugin is missing. @ line 60, column 12
[WARNING] 'build.plugins.plugin.version' for org.antora:antora-maven-plugin is missing. @ line 38, column 12
[WARNING] 
[WARNING] Some problems were encountered while building the effective model for org.springframework.ai:spring-ai-autoconfigure-retry:jar:1.0.0-SNAPSHOT
[WARNING] The expression ${parent.version} is deprecated. Please use ${project.parent.version} instead.
[WARNING] 
[WARNING] Some problems were encountered while building the effective model for org.springframework.ai:spring-ai-couchbase-store:jar:1.0.0-SNAPSHOT
[WARNING] The expression ${parent.version} is deprecated. Please use ${project.parent.version} instead.
[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.
