docs(linter): Add configuration option docs for import/no-duplicates rule.

[connorshea]

Part of #14743.

Generated docs:

## Configuration

This rule accepts a configuration object with the following properties:

### preferInline

type: `boolean`

default: `false`

When set to `true`, prefer inline type imports instead of separate type import
statements for TypeScript code.

Examples of **correct** code with this option set to `true`:
\```typescript
import { Foo, type Bar } from './module';
\```

Pull Request Overview

This PR adds schema configuration support for the no-duplicates import rule, enabling the preferInline option to be properly documented and validated through JSON schema. This allows users to configure whether TypeScript code should prefer inline type imports over separate type import statements.

• Added JsonSchema derive and serde attribute to the NoDuplicates struct
• Added documentation for the prefer_inline field
• Registered the configuration in the declare_oxc_lint! macro
