fix(telegram): recover from grammY long-poll timeouts (#7466) (thanks @macmimi23)

grammY getUpdates returns "Request to getUpdates timed out after 500 seconds"
but RECOVERABLE_MESSAGE_SNIPPETS only had "timeout". Since
"timed out".includes("timeout") === false, the error was not classified as
recoverable, causing the polling loop to exit permanently.

Add "timed out" to RECOVERABLE_MESSAGE_SNIPPETS so the polling loop retries
instead of dying silently.

Fixes #7239
Fixes #7255
