fix: lock rke2-common and pin rke2 to 1.33.13~rke2r2 to unblock puppet (#516)

## Why

Every puppet run on k8s nodes (e.g. prodnxsr0002) fails on `Package[rke2-server]` and stops applying the rest of the catalog, so the nodes stop receiving all further package/config updates:

```
change from '1.33.4~rke2r1-1.el9' to '1.33.11~rke2r1' failed: Could not update:
dnf upgrade rke2-server-1.33.11~rke2r1 returned 1:
 Problem: problem with installed package rke2-common-1.33.13~rke2r2-0.el9.x86_64
  - package rke2-server-1.33.11~rke2r1 requires rke2-common = 1.33.11~rke2r1, but none of the providers can be installed
  - cannot install the best update candidate for package rke2-server
```

`rke2::install` versionlocks only `rke2-server`/`rke2-agent`, never their strict (`= version`) `rke2-common` dependency. `rke2-common` is served from the rolling `rancher-rke2-1.33-latest` channel, whose head is now `1.33.13~rke2r2`, so `rke2-common` drifted up to `1.33.13~rke2r2` while the pin (`#512`) sat at `1.33.11~rke2r1`. `dnf upgrade` cannot downgrade the newer `rke2-common` to satisfy the older server, so the transaction fails. This is the rolling-channel drift `#512` flagged as needing follow-up.

## How

- Versionlock `rke2-common` to the same `${rke2_version}~${rke2_release}` as the server/agent, so the rolling channel can no longer drift the dependency ahead of the pin.
- Bump `rke2_version` `1.33.11` -> `1.33.13` and `rke2_release` `rke2r1` -> `rke2r2` to match the current channel head and the already-drifted installed `rke2-common`, so the pinned server/agent, both versionlocks, and the preloaded airgap bundle resolve in one transaction.

Verified against the live artifactapi rke2 remote: `rke2-server-1.33.13~rke2r2-0.el9.x86_64.rpm` and the `v1.33.13+rke2r2` `rke2-images.linux-amd64.tar.zst` airgap bundle both serve HTTP 200.
