[bug] handle correct the max_nominations related to the validators set.

[pepoviola]

This config with 10 validators will try to create nominators with a max nominations of 24 (our default) and will break the chain-spec (with nulls). We should handle and set the max_nominations related to the validators set.

Here we set the max_nominations value https://github.com/paritytech/zombienet/blob/main/javascript/packages/orchestrator/src/configGenerator.ts#L118 but we should validate it after compute the validator set.
