Bump git-commit-id-plugin version
Bump git-commit-id-plugin version

Fixes this error:

    [ERROR] Failed to execute goal pl.project13.maven:git-commit-id-plugin:2.1.5:revision (generate-git-hash) on project neo4j-kernel: .git directory could not be found! Please specify a valid [dotGitDirectory] in your pom.xml -> [Help 1]

This makes it possible to build the individual modules again, because this newer version of the plugin will find the .git directory recursively:

    cd community/kernel && mvn clean package
