Error in plugin hardhat-vyper: File should always be found

[pcaversaccio]

Version of Hardhat

2.22.5

What happened?

When I pushed the upgrade to Vyper version 0.4.0 here pcaversaccio/zksync-vyper-sandbox@83b79c8, the compilation started to fail with:

Solidity 0.8.26 is not fully supported yet. You can still use Hardhat, but some features, like stack traces, might not work correctly.

No need to generate any newer typings.

@kiriyaga-txfusion thanks for the fix and @alcuadrado for the quick release. Quickly tested and successfully deployed a 0.4.0 ZKsync Vyper contract here: https://sepolia-era.zksync.network/address/0x0E74203a877C6f681491388Bbd9bde4d0589C8e9#code.

We need to address another issue tho (will open a new issue) re verification of Vyper contracts that use modules. But that's for the other issue.
