Increase latchable timeout to 20s for ForcePushDownNestedQueryTest (#18816)

The MSQ query appearst to take longer than 10s. Other tests like QueryVirtualStorageTest
and EmbeddedDurableShuffleStorageTest that use the same query use 20s timeout, so that should help.

Also, include the timeout in the error message so it's clear rather than having to look at the
stacktrace.
