Please transfer publisher of checkbox-ce-oem

Hi @reviewers, I have a snap checkbox-ce-oem registered with ce-qa@lists.canonical.com account as publisher but now I’d like to transfer it to ce-certification-qa

This is a checkbox test suite used by OEM QA team for commercial project testing, and it’s now also hosted on the same GH repo as the generic checkbox (https://github.com/canonical/checkbox/tree/main/contrib/checkbox-provider-ce-oem)

The snap checkbox-ce-oem was transferred to ce-certification-qa. It was already set as collaborator, so no further checks were needed before the transfer.
