I propose renaming rsconnect deploy api to rsconnect deploy flask.

• Now that FastAPI is supported, it is confusing that the command to deploy a flask API is called api (all of the other deploy commands use the framework name).
• The help message is also confusing and does not mention Flask (e.g. Deploy a Python API to Posit Connect [v1.8.2+], Posit Cloud, or shinyapps.io.. It is unclear to users what a "Python API" is.
• This can be done so that backwards compatibility is not broken, but we only document and recommend rsconnect deploy flask.

Commencez au point d’entrée de la commande rsconnect deploy, en particulier avec le sous-commande api existante et son texte d’aide. Suivez l’endroit où la commande est enregistrée et documentée, puis vérifiez que flask est le nom recommandé, que api reste rétrocompatible et que le texte d’aide identifie clairement Flask.
