ParameterDeclaration[] is not assignable to type 'OptionalKind<ParameterDeclarationStructure>[]'

**Describe the bug**

I try to pass parameters from `foo` method to `bar` method.
```
const cls = sourceFile.getClasses()[0];
const params = cls.getMethods()[0].getParameters();

sourceFile.addClass({
name: "bar",
methods: [{ name: "bar", parameters: params }] // <--- Not match. why??
});
```

But I got a typescript error:
```
Type 'ParameterDeclaration[]' is not assignable to type 'OptionalKind[]'.
Type 'ParameterDeclaration' is not assignable to type 'OptionalKind'.
Property 'name' is missing in type 'ParameterDeclaration' but required in type 'Pick'
```

Is there another way to do it?

"test.ts",

}
}
`
);

const cls = sourceFile.getClasses()[0];
const params = cls.getMethods()[0].getParameters();

sourceFile.addClass({
name: "bar",
methods: [{ name: "bar", parameters: params }] // <--- Not match. why??
});
