feat: add tenant CRD to e2e artifact collection and debug report (#787)

## Summary
Add the `tenants.maas.opendatahub.io` CRD to e2e must-gather artifact
collection and the auth debug report.

## Description
The Tenant CRD was recently introduced but was missing from the e2e
debugging and artifact-collection utilities in `auth_utils.sh`.

- Add `tenants.maas.opendatahub.io` to the `MAAS_CRDS` array so
`collect_maas_crs()` dumps Tenant CR YAML to `tenants.yaml`.
- Add `kubectl get tenants` to `collect_cluster_state()` alongside other
MaaS CRs.
- Add Tenant listing and status/condition detail to
`run_auth_debug_report()` under the MaaS CRs section.
- Update header comment to document the new `tenants.yaml` artifact.

## How it was tested
- Verified script syntax with `bash -n`.
- Confirmed the Tenant CRD name matches
`deployment/base/maas-controller/crd/bases/maas.opendatahub.io_tenants.yaml`.
- Confirmed namespace usage aligns with
`TenantReconciler.TenantNamespace` (sourced from
`--maas-subscription-namespace`).
