Running hardhat trace --hash on arbitrum nova fails "block has a different hardfork than the vm"

[kasumi-1]

I believe the fix is to add skipHardForkValidation: true, to the following two lines:

hardhat-tracer/src/tasks/trace.ts

Line 245 in 21c2b2d

await vm.runTx({ tx: txWithCommon, block });

hardhat-tracer/src/tasks/trace.ts

Line 248 in 21c2b2d

await vm.runTx({ tx: txWithCommon, block });

It looks like hardhat also skips this validation in some spots, but I am unfamiliar enough with codebase to not know if this could cause issues without some other check in place. The above change worked for me locally.

Thanks for reporting, I've added the fix and published in 2.3.1. Do let me know if there are any issues with it.
