docs(linter): Add configuration option docs for import/no-duplicates rule. (#15137)

Part of #14743.

Generated docs:

```md
## 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';
\```
```
