Wrong seat price computation with stateless validation feature enabled

[telezhnaya]

My validator on StatelessNet is shown as the one to be kicked off for more than a week, while I'm successfully validating all this week.

We need to change the logic for max_number_of_seats
https://github.com/near-cli-rs/near-validator-cli-rs/blob/main/src/proposals/mod.rs#L136
https://github.com/near-cli-rs/near-validator-cli-rs/blob/main/src/validators/block_id/mod.rs#L86
(maybe somewhere else)

It surely should take into account protocol_config. num_chunk_only_producer_seats. But I'm still not sure about the resulting formula. Let's wait for the updates on Zulip and then we can create a fix for this.
