Error: You are not authorized to use this API.

The version of capibmadm - 0.5.0 does not have the fix for the above issue.

@mkumatag, since the cherry-pick is failing with a conflict, I decided to submit the fix against branch 0.5.
However, in the E2E tests, capibmadm binary is downloaded from GitHub release artifacts. Should we create a new 0.5.x release or consider building capibmadm from main from here on? wdyt?

I feel its good to build locally and use that one, otherwise it is going to be challenging always.
