feat: add hugegraph-ldbc

[Zony7]

Purpose of the PR

Main Changes

The aim of this PR is to enable the execution of LDBC SNB (Social Network Benchmark) tests on HugeGraph. To achieve this, I have made modifications to certain portions of the code related to the workload and Gremlin query statements. Additionally, I have authored a README document to provide clear instructions on the testing process. These changes ensure that the LDBC tests can be executed successfully.
