add some swagger UI function to ui.run() (#4050)

Add some params to ui.run().
You can add more params into Swagger UI, such as project title,
description, version, etc.
Like this:
```python
ui.run(
        title=siteName, #If the title of the document is not defined separately below, it will default to following this parameter.
        native=False,
        language='zh-CN',
        fastapi_docs=True, #Only if this parameter's value is True will the following content be displayed.
        fastapi_docs_title='NiceGUI',
        fastapi_docs_description='some description',
        fastapi_docs_version='2.5.0',
        fastapi_docs_terms_of_service='https://nicegui.io',
        fastapi_docs_contact={
            'name': 'zauberzeug', 
            'url': 'https://nicegui.io', 
            'email': 'example@example.com'
            },
        fastapi_docs_license_info={
            'name': 'MIT',
            'url': 'https://www.example.com',
        })
```
