It would be better to include all active PrecompiledContracts from 0x01 for this hardfork, if the name is based on the hardfork.

[nits] It may be clearer to handle the full precompile set in the switch case for each hardfork, rather than looking up Prague and Osaka precompiles separately after the switch.

This pull request introduces support for two new Ethereum hard forks, Prague and Osaka, by updating the chain configuration, fork activation logic, precompiled contract sets, and related tests. The changes ensure that the new forks are correctly ordered after Berlin, add their activation checks, and extend the precompile contract logic to include new contracts for these forks.
Fork support and configuration:
PragueBlockandOsakaBlockfields to theChainConfigstruct, along with corresponding activation checks (IsPrague,IsOsaka) and fork ordering validation inCheckConfigForkOrder. Also updated the string representation and compatibility checks to include these new forks.Precompiled contracts and fork activation:
PrecompiledContractsPragueandPrecompiledContractsOsakafor the new forks. Updated the logic for active precompiles and EVM precompile lookup to include Prague and Osaka contracts when their forks are active.Chain config presets:
