[Improve] Upgrade HBase version and replace custom hbase-shaded-endpoint with official artifacts

[vaijosh]

Feature Description (功能描述)

Currently, HugeGraph uses a custom hbase-shaded-endpoint for HBase connectivity.

To align with the official Apache HBase ecosystem and simplify dependency management, we need to upgrade the HBase latest stable version 2.6.5 and use the standard official artifacts instead of custom hbase-shaded-endpoint

Proposed Changes

• Upgrade HBase version: Move to the latest stable HBase 2.x version.
• Replace Dependencies: * Remove: com.baidu.hugegraph:hbase-shaded-endpoint (or current internal group) and use equivalent official Hbase artifacts

Impact
Better long-term support, security patches from the official HBase project, and reduced maintenance overhead for custom shaded jars.
