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

testcontainers.core.waiting_utils の wait_for_logs から始め、ログが一致するのを待っている間に DockerContainer の状態がどのように確認されているかを調べます。flyway/flyway を使って例を再現し、述語が一致する前にコンテナが終了した場合の期待される動作を確認します。コンテナの終了後、タイムアウトまで待機が継続しなくなれば完了です。
