Looks like serverTaskWaiter.waitForTasks clears the "timeout" timeout immediately (in finally block).

I have added a comment to an issue in await-task-action, see: OctopusDeploy/await-task-action#22 (comment)

The await-task-action timeout value does not seem to do anything, and even the default value (600s) does not seem to work.
That action code uses the api-client's serverTaskWaiter to wait for tasks...

Looking at the serverTaskWaiter code it appears there is a bug where the timeout is cleared in a finally block immediately on the first wait loop iteration.

api-client.ts/src/features/serverTasks/serverTaskWaiter.ts

Lines 83 to 85 in 1f265ed

	} finally {
	clearTimeout(t);
	}

Meaning the timeout period is effectively not used and the wait loop will go forever (or until the tasks complete).
