Octokit.VERSION "4.0.4"

What happened?

When invoking create workflow dispatch for a specific workflow on a specific branch, it yields a 404. The workflow is only present on the specific branch.

> await octokit.request("POST /repos/OWNER/REPO/actions/workflows/workflow.yml/dispatches", {ref: "refs/heads/some-branch-name", inputs: {}})
request { method: 'POST',
  baseUrl: 'https://api.github.com',
  headers: 
   { accept: 'application/vnd.github.v3+json',
     'user-agent': 'octokit.js/2.0.7 octokit-core.js/4.0.4 Deno/1.24.3' },
  mediaType: { format: '', previews: [] },
  request: { hook: [Function: bound bound register], retryCount: 1 },
  url: '/repos/OWNER/REPO/actions/workflows/workflow.yml/dispatches',
  ref: 'refs/heads/some-branch-name',
  inputs: {} }

Also tried with numeric id instead of yml filename.

The expected behavior (as with gh-client) is a 204 response:

It seems that the ref param is not correctly passed. Tried with both a simple branch name as the shown git ref specifier.

Unfortunately, I was not able to get the exact http request to be logged.

Would you be interested in contributing a fix?
