fix(types): Toast component

[mxschmitt]

I don't know how to fix this, but that's at least the test for it.
Would be cool if someone could help me :)

show and transition aren't marked optional in

react-bootstrap/types/components/Toast.d.ts

Lines 13 to 14 in 04aed51

	show: boolean;
	transition: boolean | React.ElementType;

Is that intentional? That's the error you're seeing.

I don't think so, because we provide defaultProps there. So true for show and Fade for transition. I've adjusted it.

And thanks @taion!
