Keyword arguments are not supported for Events

[bertbarabas]

Describe the bug
When yielding a server event with a keyword argument from a server event, the type checker complains with:

Unexpected keyword argument `tries` in function `reflex_base.event.EventCallback.__call__`

To Reproduce
Just paste the code below into your code editor with type checking enabled and note the underlined keyword as shown in the screen shot.

• Code:

import reflex as rx


class MyState(rx.State):
    @rx.event
    def do_something(tries=1):
        # yield something to client
        if tries > 0:
            yield MyState.do_something(tries=tries - 1)

Expected behavior
There should not be any type check errors
