test(crypto): CRP-2058: Increase min subnet size in flaky test

The `create_transcript::should_fail_create_transcript_with_disallowed_dealer` test was flaky since it generated a subnet of size `(1..10)`, then removes a dealer, and then creates `IDkgTranscriptParams` with the rest of the nodes in the subnet as dealers. If the initial subnet size was 1, then `IDkgTranscriptParams` will be generated with a BTreeSet of size 0, which panics. This MR increases the minimum subnet size to 2.
