fix(ci): Fix build docker image error

[fangyinc]

Description

Previously, the DB-GPT docker image build failed due to the large disk space occupied, such as https://github.com/eosphoros-ai/DB-GPT/actions/runs/11967971790

I fixed it according to https://github.com/orgs/community/discussions/26351#discussioncomment-3251595
