Addressing the build failure due to gradle version upgrade. From https://github.com/opensearch-project/performance-analyzer-rca/actions/runs/4833884278/jobs/8815180043:

* What went wrong:
A problem was found with the configuration of task ':clonePaGitRepo' (type 'GitClone').
  - Type 'org.ajoberstar.gradle.git.tasks.GitClone' property 'authentication' is missing an input or output annotation.
    
    Reason: A property without annotation isn't considered during up-to-date checking.

Describe the solution you are proposing
Removing the redundant git clone and replacing with pulling Snapshots from Maven Snapshot repo(https://aws.oss.sonatype.org/content/repositories/snapshots). Refer: https://opensearch.org/blog/opensearch-plugin-zips-now-in-maven-repo/
