Bug 1936066 [wpt PR 49592] - Remove exception from requestClose, a=testonly

Automatic update from web-platform-tests
Remove exception from requestClose

See this conversation:

https://github.com/whatwg/html/pull/10737/files#r1873864137

There doesn't seem to be a reason to require `closedby` to be used
in order for `requestClose()` to work.
