Review component_vue decorator.

[maartenbreddels]

@mariobuikhuizen I took the opportunity to implement the decorator we desperately needed to avoid boilerplate in 9b47b519538a22feec72549af1e6d58fcad0c18d:

@solara._component_vue("algolia.vue")
def Algolia(app_id: str, index_name: str, api_key: str, debug=False):
    pass

which I used in 7793e765708ff7bf04dd246a5fae33b35f2009dc

I think we should review this together and remove the underscore
