chore: bump Solidity to 0.8.25

[smartcontracts]

Bumps the Solidity version to 0.8.25. Starting work on a larger migration of the entire Solidity codebase to 0.8.25 and this is one of the holdouts.

[smartcontracts]

Switching to draft for now, need to get approval on this

Can this get revisited and approved? It's required for https://github.com/ethereum-optimism/optimism/issues/11527 to be implemented.

I think using loose versioning (^0.8.0) would be better in this case so it does not need to be changed in the future and can be used without a strict version constraint on other codebases

We should use ^0.8.0 here for sure for the versions
