Updated test expectations at https://trac.webkit.org/changeset/281519/webkit.

The flaky timeout is seen on BigSur wk1 Debug as well. It looks like this test is generally slow with about 20 seconds to run. When this test times out on BigSur wk1 Debug, it takes about 30 seconds. I will mark this test as slow on macOS. 

Will leave the previously marked test expectations on BigSur wk2 Debug as is because when the test times out on wk2, it takes ~99 seconds.
