feat: Set `timeout` flag when `wait-until` timeouted

[cadavre]

Very simple, yet helpful addition to wait-until node's timeout output.

Sometimes this node is a beginning to a big flow that may run some portion if state timeout'd. Both outputs may connect to the same next node, but it may be a switch that performs slightly different actions on state reached or timeout.

I'm not sure if I made the addition in a correct place and, true – I haven't tested this locally – but that effort would be much bigger than just creating this PR. Therefore I ask for your understanding. :)

Summary by CodeRabbit

• New Features
  • Output context now explicitly indicates when a wait-until node times out, providing clearer feedback for timeout events.
• Documentation
  • Updated the "Wait Until" node documentation to include the new timeout output property and improved descriptions.

## Walkthrough

A new property, `timeout: true`, is added to the context object passed to the `setCustomOutputs` method within the timeout callback of the wait-until node. This change explicitly signals that the output was triggered by a timeout event, without altering any other logic or control flow.
