[False Negative]: Not show the correct report on unused imports

### What bug did Slither miss and which detector did you anticipate would catch it?

I have unused imports and it doesn't detect them.

`slither . --skip-assembly --detect "unused-import"`

### Frequency

Very Frequently

### Code example to reproduce the issue:

pragma solidity ^0.8.26;

import {FixedPointMathLib} from "solady/utils/FixedPointMathLib.sol";
import {IPoolManager} from "v4-core/interfaces/IPoolManager.sol";
import {Hooks} from "v4-core/libraries/Hooks.sol";
import {LPFeeLibrary} from "v4-core/libraries/LPFeeLibrary.sol";
import {StateLibrary} from "v4-core/libraries/StateLibrary.sol";
import {BeforeSwapDelta, BeforeSwapDeltaLibrary} from "v4-core/types/BeforeSwapDelta.sol";
import {Currency, CurrencyLibrary} from "v4-core/types/Currency.sol";
import {PoolId, PoolIdLibrary} from "v4-core/types/PoolId.sol";
import {PoolKey} from "v4-core/types/PoolKey.sol";
import {BaseHook} from "v4-periphery/BaseHook.sol";

### import {MyImport} from "./MyImport.sol"; <---- this unused import

### Version:

slither --version
0.10.3
