[Hardhat] Fix No known hardfork for execution on historical block problem

[acuarica]

When running a test against a "not" well-known forked network, Hardhat raises the following error

     ProviderError: No known hardfork for execution on historical block 10016755 (relative to fork block number 10016755) in chain with id 296. The node was not configured with a hardfork activation history.

Given the following issues, it looks like some sort of Hardhat regression

• Hardfork activation history not working on polygon fork NomicFoundation/hardhat#2396
• No known hardfork for execution on historical block NomicFoundation/hardhat#5511

That's why we had to add hre.network.provider.send('hardhat_mine', ['0x001']) in our Hardhat tests as a workaround.

The issue for Optimism and Arbitrum was fixed here (as a temporary workaraound)

• Add hardfork histories for opt and arb mainnet/sepolia NomicFoundation/hardhat#5394

However, the definitive fix to this problem is being tracked here

• Better handling of unknown hardfork histories NomicFoundation/edr#522

In any case, for our purposes we need to setup a hardfork in the plugin so we free our users to do so. See https://hardhat.org/hardhat-network/docs/guides/forking-other-networks#using-a-custom-hardfork-history for more details.

We can think of sending a PR to Hardhat's repo so they can add Hedera chains as well in the future.

Note

I tried to setup the chains config for Hedera networks within extendProvider, but it didn't work. I guess we need to use extendConfig to fill in the hardfork chains early in the setup process.
