Patryk Jędrzejczak 1f28a55448 test: test_tablets_parallel_decommission: prevent group0 majority loss ...

Both of the changed test cases stop two out of four nodes when there are
three group0 voters in the cluster. If one of the two live nodes is
a non-voter (node 1, specifically, as node 0 is the leader), a temporary
majority loss occurs, which can cause the following operations to fail.
In the case of `test_tablets_are_rebuilt_in_parallel`, the `exclude_node`
API can fail. In the case of `test_remove_is_canceled_if_there_is_node_down`,
removenode can fail with an unexpected error message:
```
"service::raft_operation_timeout_error (group
[46dd9cf1-fe21-11f0-baa0-03429f562ff5] raft operation [read_barrier] timed out)"
```

Somehow, these test cases are currently not flaky, but they become flaky in
the following commit.

We can consider backporting this commit to 2026.1 to prevent flakiness.
