please remove redundant /// <reference types="react" /> (breaks preact)

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used [patch-package](https://github.com/ds300/patch-package) to patch `react-feather@2.0.10` for the project I'm working on.

Here is the diff that solved my problem:

import { FC, SVGAttributes } from 'react';

export interface IconProps extends SVGAttributes {
```

This issue body was [partially generated by patch-package](https://github.com/ds300/patch-package/issues/296).

## Reasoning:

That directive force-includes the full `@types/react` package into the TypeScript program's global type set. If a project aliases `react` to
`preact/compat` (in tsconfig `paths`), pulling in the real React global types clashes with the preact/compat JSX runtime under `exactOptionalPropertyTypes`.

The directive is redundant (I think): the `import { FC, SVGAttributes } from 'react'` on the next line already resolves to preact/compat through the path alias, which provides both types.

### Reproducer:

```jsx
import * as React from "preact";
import {Upload} from "react-feather";

export function F() {
return
}
```

Error message:

```
'Upload' cannot be used as a JSX component.
Its type 'Icon' is not a valid JSX element type.
Type 'FunctionComponent' is not assignable to type 'FunctionComponent' with 'exactOptionalPropertyTypes: true'. Consider adding 'undefined' to the types of the target's properties.
Types of property 'displayName' are incompatible.
Type 'string | undefined' is not assignable to type 'string'.
Type 'undefined' is not assignable to type 'string'.

Start with the published declaration at node_modules/react-feather/dist/index.d.ts and compare it with the package source or build entry that generates it. Use the provided Preact alias reproducer with exactOptionalPropertyTypes enabled; done means the published declarations no longer force React's reference types and the reproducer type-checks without the JSX component error.
