@layerzerolabs/lz-evm-oapp-v2 uses dependency with outdated ethers@5 peer dependency

[actuallymentor]

When installing @layerzerolabs/lz-evm-oapp-v2 with the latest hardhat, one encounters a peer dependency conflct.

It looks like layerzerolabs/lz-evm-oapp-v2 depends on @layerzerolabs/lz-evm-messagelib-v2, which depends on @eth-optimism/contracts@"^0.6.0, which depends on ethers@5.7.2.

While this error can be ignored with --legacy-peer-deps it is probably a good idea to fix the underlying dependencies or add this to a Known Issues section so as to not confuse/worry developers trying out the oApp contracts.
