Increase timeout for TestAccEcsParallel (#1489)

This test verifies that components like ECS services are created/updated
in parallel. This took 1+ hours to run before fixing pulumi/pulumi#7629.
The test started to become more flaky recently (see
#1488), this coincides with
upgrading the GitHub runners to Ubuntu 24.04 and onboarding awsx to
ci-mgmt. Those changes might've affected the test runtime and 15 minutes
were probably a bit too aggressive.
Updated the timeout to 30min, which is still well below the 1 hour it
took before.

Fixes #1488
