Bug: `testcontainers.core.waiting_utils.wait_for_logs` keeps waiting despite the container has exited.

Describe the bug

The testcontainers.core.waiting_utils.wait_for_logs keeps waiting despite the container has exited. This can be confusing if there is a long wait time.

To Reproduce

from testcontainers.core import container, waiting_utils

if __name__ == "__main__":
    waiting_utils.wait_for_logs(
        container.DockerContainer("flyway/flyway").start(),
        r"Successfully applied \d+ migrations to schema",
        timeout=large_n, # 
    )

# >> Raised Exception has occurred: TimeoutError Container did not emit logs satisfying predicate in `large_n` seconds

Runtime environment

Python:         3.11.9
testcontainers  4.7.2
Implementation: CPython

从 testcontainers.core.waiting_utils 中的 wait_for_logs 开始，检查在等待匹配的日志时如何检查 DockerContainer 的状态。使用 flyway/flyway 重现该示例，并确定容器在 predicate 匹配之前退出时的预期行为。当容器退出后等待不再持续到 timeout 时，即表示完成。
