Feature request: Parameters for automations

[michalczerwinski]

I really like automations in GitHub Copilot. But I am missing some parameters.
Would be nice to be able to define some parameters (repo name, service name, input file, etc) and use them in prompt like $repo_name, $input_file

When executing automation the app should display the dialog to ask user about parameters.
Would be also nice to have some notion of types per param (file, directory, text line, text area, etc)
