[hotfix][gbase] Fix gbase driver link

[zhangshenghang]

Purpose of this pull request

The previous gbase link is invalid,
return "https://cdn.gbase.cn/products/30/p5CiVwXBKQYIUGN8ecHvk/gbase-connector-java-9.5.0.7-build1-bin.jar";
cause ci error

Access link access prompt 403

Reason:
The download link provided by the manufacturer has been modified. I found that it is necessary to add sign and t to the link as verification when downloading from the official website https://www.gbase.cn/download/gbase-8a?category=DRIVER_PACKAGE. These two parameters are time-sensitive.

Solution:
Download gbase-connector-java-9.5.0.7-build1-bin.jar from other channels
