Target Osaka EVM during tests

[Amxx]

Fusaka (Osaka) was activated on Mainnet a few weeks ago. Until today, the run all our tests using Pectra (Prague).

Osaka comes with some significant changes to the execution layer

• EIP-7825 limit the size of transactions to 2**24 gas (16.7m).
• EIP-7935 increases the block size limit from 30m to 60m.
• EIP-7951 enables the secp256r1 precompile (that our code also look for, but that was so far not present on mainnet)
• EIP-7939 adds the new CLZ opcode
• EIP-7823 sets an upper bound for the MODEXP precompile.

In order to enable that this EVM version, this PR bumps the version of hardhat to use an EDR that supports it.
This PR also sets a newer version of the compiler that support Osaka as a target.

Unfortunatelly, some of the EIP is Fusaka are breaking our code/tests. We need to figure out how to address that.
