Show the original error message from GitHub on Admin Check

Description

The message for when the admin check fails makes some assumptions about the API response, but we should include the full API response to help debugging.

@ianthomas23, from what I can tell we are logging the full response,

jupyter_releaser/jupyter_releaser/util.py

Line 610 in 2fc7de9

collab_level = gh.repos.get_collaborator_permission_level(user)

.

Can you post a link to your workflow run here?

@blink1073 https://github.com/ipython/ipykernel/actions/runs/9699310606/job/26767956167 is the latest run in which the Admin check failed.

Oh, right, that was before we backported the workflow changes. I realized what went wrong after that, we needed to set the branch field in the dialog. I opened #581 to properly handle the case where you run the workflow against a different branch.
