Automatically send project_id to be part of prompt

Problem

Currently Duo Workflow can only be used from the context of a specific project. It is reasonable to assume that any query towards Duo Workflow is associated with the current project. Originally, the placeholder text for the goal prompted the user to add a project_id, but project_id is not something a user necessarily automatically knows, nor should they have to enter it since it can be inferred.

At the same time, the project_id can give Duo Workflow hints in which project to search for associated issues or similar.

Desired Outcome

project_id is automatically sent along to Duo Workflow service to be included in prompt(s), and used accordingly.

Proposed Solution

TBD - project_id is available in the LSP and also Rails.
