Empty git.properties is generated in submodules when injectAllReactorProjects=true starting from 8.0.0

[KTannenberg]

Describe the bug (required)

When running git-commit-id-plugin on a multi-module maven project with a parent pom and injectAllReactorProjects set to true, all generated git.properties in submodules will end up with no content.

This bug affects versions 8.0.0+ of plugin, version 7.0.0 is the latest not affected one.

Tell us about the Plugin version used (required)

7.0.0, 8.0.2, 9.0.0

Tell us about the Maven version used (required)

Apache Maven 3.9.6 (bc0240f3c744dd6b6ec2920b3cd08dcc295161ae)
Maven home: /home/john.doe/.sdkman/candidates/maven/current

Steps to Reproduce (required)

Clone repository

Run maven initialize and check contents of generated git.properties files

mvn clean initialize

# non-empty diff as module1's file only contains header comment
diff -u target/classes/git.properties module1/target/classes/git.properties

Re-run with version 7.0.0 of plugin

mvn clean initialize -Dgit-commit-id-maven-plugin.version=7.0.0

# no differences between the files
diff -u target/classes/git.properties module1/target/classes/git.properties
