Create workflow for non-blazor issues for triage & plan of action agent

[wadepickett]

Goal:

AI triage and assesment for non-blazor content for issues as they are cr, thank the issue creator and indicate help will be along soon.
Assign a label ai-triage-action-plan indicating an AI triage report has been run for the issue.
Run a specified agent that will create the report and enter it into the issue discussion.

Put the new workflow file here:
https://github.com/dotnet/AspNetCore.Docs/tree/main/.github/workflows

name it: issue-processing-ai-triage-nonblazor.yml

Here is a draft worflow .yml for this to be added as a new workflow in this repo:
