[BUG] [CI] Maven cache key collision causes flaky e2e-case failures

[eye-gu]

Is there an existing issue for this?

Current Behavior

https://github.com/apache/shenyu/actions/runs/27494862854/job/81267317313?pr=6347

Could not find artifact org.apache.shenyu:shenyu-spring-boot-starter-client-springmvc:jar:2.7.1-SNAPSHOT

ci and e2e-k8s workflows share the same cache key: key: ${{ runner.os }}-maven-${{ hashFiles('**/pom.xml') }}.
But ci not install. The e2e-k8s jobs subsequently restore the incomplete cache from ci.yml, and fail when building shenyu-examples which depends on SNAPSHOT jars not present in the cache.
