(fix) no error for component typedef with event

[jasonlyu123]

For the new transformation. Currently, it would show an error with a component having events in the typedef. For example:

class Component extends SvelteComponentTyped<{}, { click: MouseEvent }, {}>{}

Thanks!

For my future self, this is the error that would appear:
