[Wasm] Reduce max length on browser for ToArrayShouldWorkWithSpecialLengthLazyEnumera...

Addresses the occasional timeouts in System.Linq tests.  The last 3-4 iterations of ToArrayShouldWorkWithSpecialLengthLazyEnumerables take
between 20 - 56 seconds each and likely trigger longer GC runs.

Fixes https://github.com/dotnet/runtime/issues/41114
