feat: add Microsoft Stream video component

[gaelhameon]

Hi ! Thanks for this project ! I'd like to use it to embed videos hosted on Microsoft Stream so I added a component. Right now, I only created the Video component, but there are other objects in Microsoft Stream that can be embedded, like channels and groups, so I tried using a folder structure and naming convention that would make it easy to add those in the future. And I haven't looked into it too much yet, but I think it's possible to embed media from other Microsoft products too, so I created a specific folder for Stream.

I havent found any public stream videos and I don't think such a thing exists. I've limited the integration tests to checking if the sign in buttons appear. Locally, it works fine after that when I log in to stream with my company's credentials.
