Patch docs git commit

[johnnydacosta]

Simply adding the git-commit-id-maven-plugin plugin to your POM will not generate the git.properties file by default. We must explicitly configure the plugin’s and sections to enable generation during the build lifecycle.
The block binds the plugin goal to the initialize phase, ensuring the Git information is captured early in the build.
The block enables the creation of the git.properties file with full commit details at the specified location.

Thanks for the proposal, but similar configuration is already provided by spring-boot-starter-parent:

<plugin>
    <groupId>io.github.git-commit-id</groupId>
    <artifactId>git-commit-id-maven-plugin</artifactId>
    <executions>
        <execution>
            <goals>
                <goal>revision</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <verbose>true</verbose>
        <generateGitPropertiesFile>true</generateGitPropertiesFile>
        <generateGitPropertiesFilename>${project.build.outputDirectory}/git.properties</generateGitPropertiesFilename>
    </configuration>
</plugin>

The documentation already mentions the role that the starter parent plays:

For Maven users, the spring-boot-starter-parent POM includes a pre-configured plugin to generate a git.properties file
