Re: [I] There is now multiple build WARNING output on every use of `exportAntProperties` as of 3.2.0 [maven-antrun-plugin]

   In the open PR, it may not be necessary to do a value comparison between the ANT property and the corresponding Maven property, if it exists.
   
   Based on a simple test, it doesn't seem possible to override a Maven property from the antrun plugin, even with the [`<local>` task](https://ant.apache.org/manual/Tasks/local.html).
   
   This sample POM demonstrates the immutable behavior:
   ```
   <?xml version="1.0" encoding="UTF-8"?>
   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
     <modelVersion>4.0.0</modelVersion>
     <groupId>my.groupId</groupId>
     <artifactId>my-artifactId</artifactId>
     <version>1.0</version>
     <packaging>pom</packaging>
     <properties>
       <some.property>maven</some.property>
     </properties>
     <build>
       <plugins>
         <plugin>
           <artifactId>maven-antrun-plugin</artifactId>
           <version>3.2.0</version>
           <executions>
             <execution>
               <id>print-property</id>
               <phase>verify</phase>
               <goals>
                 <goal>run</goal>
               </goals>
               <configuration>
                 <target>
                   <echo level="info">some.property (maven): ${some.property}</echo>
                   <property name="some.property" value="ant"/>
                   <echo level="info">some.property (ant): ${some.property}</echo>
                   <local name="some.property"/>
                   <property name="some.property" value="local"/>
                   <echo level="info">some.property (local): ${some.property}</echo>
                 </target>
               </configuration>
             </execution>
           </executions>
         </plugin>
       </plugins>
     </build>
   </project>
   ```
   
   The console output from running `mvn clean verify` with Maven 3.9.11 is:
   ```
   [INFO]      [echo] some.property (maven): maven
   [INFO]      [echo] some.property (ant): maven
   [INFO]      [echo] some.property (local): maven
   ```
   
   `some.property` is defined as a POM property and its value remains constant despite the `<property>` & `<local>` ANT tasks.
   
   Alternative ways to remove the unwanted warnings could be:
   - revert the log message back to debug, as the log level change had no obvious link to the limitation that needed to be documented in the original issue
   - completely ignore ANT properties that are also Maven properties during the export step, as their values can not be changed with this plugin
