I dislike this idea:
When I have a local dev env set up, and I start the widget yarn dev, then it will be available at http://localhost:5273/. I can /addwidget http://localhost:5273/ and use it in Element Web. Now I start the widget wit yarn dev:https, and it will be available at https://localhost:5273/. My room that already has the widget set up breaks with a http/https mismatch issue, but finding that issue is obfuscated. I check for using the right port etc, it is all correct.

Since I have to /addwidget https://something:abcd anew anyway when running in https mode, I think keeping the current state is preferable - I don't understand the benefit of using the same port for both.

We have discussed this in another PR and this change is already applied for the poll widget.

I am fine to have different ports for http/https. Just want to have the same config for all the widgets.
