fix(temporary mitigation): Skip genesis bootstrapping for statelessnet (

#11727)

This is a mitigation for the failure that is caused by the stabilization
PR #11701.

[Zulip
thread](https://near.zulipchat.com/#narrow/stream/308695-nearone.2Fprivate/topic/Cherrypicks.20to.20statelessnet.20branch/near/449016937)

Context: In statelessnet, the genesis version is above 68, so it assumes
that genesis has the congestion control is enabled and hitting an issue
that attempts to bootstrap congestion info (again) and hitting missing
state roots.

We attempted to move the version numbers for congestion control and
stateless validation back to 80 and 81 to mitigate the problem, [in this
PR](#11719) but it became
unnecessarily complex and risky.

Thus, in this PR, we simply bypass the problematic bootstrap for
statelessnet only. We moved the check for the chain id after the genesis
protocol version check so we will not run it for testnet and mainnet.
