Upgrade AD's bwc baseline version to 1.3.2 to resolve cluster join issue

Issue:
- In versions between 1.1 and 2.10, the task :adBwcCluster#twoThirdsUpgradedClusterTask fails.
- Symptoms mirror those in [OpenSearch Issue #5076](opensearch-project/OpenSearch#5076).
- Logs show nodes from old and new versions failing to join as a cluster, resulting in a "master not found" exception.

Resolution:
- Upgraded the bwc version to 1.3.2, aligning with other plugins which use 1.3+ as their baseline.
  - [Cross-Cluster Replication PR opensearch-project#469](opensearch-project/cross-cluster-replication#469)
  - [Security PR #2253](opensearch-project/security#2253)
  - [ML Commons PR opensearch-project#681](opensearch-project/ml-commons#681)
- Post-upgrade, the twoThirdsUpgradedClusterTask runs successfully, suggesting potential incompatibility between versions 1.1 and 2.10.

Testing:
- Executed `./gradlew bwcTestSuite -Dtests.security.manager=false` and all tests passed.
