Show same options for any file to add to the chat

[mdeweerd]

Issue

The user gets either of the prompts below when asking for confirmation to add a file.
It would be useful to propose all the options so that the user can select A or S.

Also, I did not find a setting in the configuration to pre-select the anwser.

Further, this triggers the idea that the configuration could also allow to set a list of files that are automatically approved for adding to the chat, but not added by default.

Add file to the chat? (Y)es/(N)o/(D)on't ask again [Yes]:
