fix(telegram): add 'timed out' to recoverable error detection

The getUpdates timeout error message uses 'timed out' but
NETWORK_ERROR_SNIPPETS/RECOVERABLE_MESSAGE_SNIPPETS only had 'timeout',
causing the error to bypass retry logic and exit the channel permanently.

Add 'timed out' to both snippet lists so these errors trigger
exponential backoff retry instead of exiting.

Fixes #4617
