Switch GH Actions trigger from repository_dispatch to workflow_dispatch to enable running branches

[janpio]

This is the newer Event for GH: https://docs.github.com/en/actions/reference/events-that-trigger-workflows#workflow_dispatch
That would then just get the current branch or commit name as ref param to trigger the "Build Windows" workflow with the workflow configuration from the branch.
You also need to add that event to the on: in the yaml, but that should already be it.

A bit effort is that it requires the workflow_id as a param on the API: https://docs.github.com/en/rest/reference/actions#create-a-workflow-dispatch-event
Not sure if that is really dynamic, but here is a GH Action in Typescript that shows it is quite straigtforward to get the ID and then use it: https://github.com/benc-uk/workflow-dispatch/blob/7ff1caf33291d1ed4001bebfa7342d5ad77eb3bf/src/main.ts#L24-L46

The workflow_id is not needed, it can be replaced with the workflow file name.

It is quite easy to do, I did it for out stale action here:

https://github.com/prisma/prisma/blob/7d36455d7304ad7b998c9e314c063aed965732e0/.github/workflows/label-stale-issues.yml#L5

For API as @carmenberndt pointed out file works! It just need the ref which is a branch name or commit to work on:

(Example request that I used in insomnia)

• Tool that sends the request is: https://github.com/prisma/engineer
• Code for the GH component is here: https://github.com/prisma/engineer/tree/master/src/github
• This is the current repository_dispatch trigger we want to replace: https://github.com/prisma/engineer/blob/6d59ac2018b16a5bcb1eda234d741ad51ccf43ad/src/release/gh_actions.rs#L81
• @dpetrick knows all about how this is deployed etc - but the initial PR changing the code should be possible standalone
