For #35052 .

Changes proposed in this pull request:

• Fixes the instability test of Doris FE.
• In Windows Server 2025 CI, org.apache.shardingsphere.test.natived.jdbc.databases.DorisFETest is not running stably because dyrnq/doris:4.0.0 is a full 11.5 GB, which can easily take more than 2 minutes to download. withStartupTimeout is useless in this scenario; the pull timeout for testcontainers can only be configured through testcontainers.properties. See https://java.testcontainers.org/features/configuration/ .
