Bug: Typechain does not populate warnings/errors if hardhat config has improper import setting

Not sure if this belongs to hardhat or typechain repo, or even if it is a 'bug' as it involves incorrectly importing a hardhat plugin, but might be noteworthy. TLDR: duplicate definition warnings not populated back to the tty

Example wrong config:

```typescript
import * as dotenv from "dotenv";

import type { HardhatUserConfig, task } from "hardhat/config";
import "@nomiclabs/hardhat-ethers";
import "@typechain/hardhat";
import * as abiExporter from "hardhat-abi-exporter";

dotenv.config();

const config: HardhatUserConfig = {
solidity: {
version: '0.8.15',
settings: {
metadata: {
bytecodeHash: 'none',
},
optimizer: {
enabled: true,
runs: 1_000,
details: {
yul: false,
},
},
outputSelection: {
'*': {
'*': [
'abi',
'evm.bytecode',
'evm.deployedBytecode',
'evm.methodIdentifiers',
'metadata',
],
'': ['ast'],
},
},
},
},
networks: {
hardhat: {
allowUnlimitedContractSize: false,
},
mainnet: {
url: `https://mainnet.infura.io/v3/${process.env.INFURA_API_KEY}`,
},
rinkeby: {
url: `https://rinkeby.infura.io/v3/${process.env.INFURA_API_KEY}`,
},
goerli: {
url: `https://goerli.infura.io/v3/${process.env.GOERLI_RPC}`,
},
},
paths: {
sources: './contracts',
tests: './test',
cache: './cache',
artifacts: './artifacts',
},
typechain: {
outDir: 'types/',
target: 'ethers-v5',
},
abiExporter: {
path: "./abis",
runOnCompile: true,
clear: true,
flat: false,
only: [],
spacing: 2,
pretty: true,
},
};

export default config;
```

Correct config:
```ts
import * as dotenv from "dotenv";

import type { HardhatUserConfig, task } from "hardhat/config";
import "@nomiclabs/hardhat-ethers";
import "@typechain/hardhat";
import "hardhat-abi-exporter";

dotenv.config();

const config: HardhatUserConfig = {
solidity: {
version: '0.8.15',
settings: {
metadata: {
bytecodeHash: 'none',
},
optimizer: {
enabled: true,
runs: 1_000,

yul: false,
},
},
outputSelection: {
'*': {
'*': [
'abi',
'evm.bytecode',
'evm.deployedBytecode',
'evm.methodIdentifiers',
'metadata',
],
'': ['ast'],
},
},
},
},

},

},
typechain: {

},
abiExporter: {
path: "./abis",
runOnCompile: true,
clear: true,

pretty: true,
},
};

export default config;
```
