Bug: SFTP test container use deprecated invocation of function wait_for_logs

[jankoprowski]

Describe the bug

During tests using testcontainers SFTP module I'm getting deprecation warning from testcontainers core module:

/.venv/lib/python3.12/site-packages/testcontainers/sftp/__init__.py:269: DeprecationWarning: The wait_for_logs function with string or callable predicates is deprecated and will be removed in a future version. Use structured wait strategies instead: container.waiting_for(LogMessageWaitStrategy('ready')) or container.waiting_for(LogMessageWaitStrategy(re.compile(r'pattern')))
 wait_for_logs(self, f".*Server listening on 0.0.0.0 port {self.port}.*")

-- Docs: https://docs.pytest.org/en/stable/how-to/capture-warnings.html
