Increase SdkDumpCi timeout from LongTimeout to ExtraLongTimeout

The test spawns a child process that does a real dotnet build of
Aspire.Hosting.csproj. LongTimeoutTimeSpan is only 60s locally, which
is insufficient when the machine is under load from concurrent tests.
ExtraLongTimeoutTimeSpan (180s local / 360s CI) gives enough headroom.
