Issue:
[backport v2.11] Editing targets for a GitRepo takes some time to delete orphaned BundleDeployments
This is a backport issue for #3437, automatically created via [GitHub Actions workflow](https://github.com/rancher/fleet/actions/runs/14885494074) initiated by @aruiz14


Original issue body:

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Current Behavior

When modifying an existing `GitRepo` that is deployed to multiple target clusters, if one of the clusters no longer matches the conditions, Fleet "undeploys" those manifests (`BundleDeployments`) included in the `GitRepo` for that cluster.
However, while the `Bundle` status is updated immediately, the corresponding `BundleDeployments` are not, which indirectly causes the `GitRepo` status to contain mismatching information, since `BundleDeployments` are used to construct it.

After some time, the offending `BundleDeployments` will be garbage-collected, causing every resource to reconcile to the desired state. However, in some cases it can take up to 10 minutes, which is undesirable as it could lead to confusion (e.g. Force Updating the `GitRepo` does not have any effect on this).

### Expected Behavior

Garbage-collection of unneeded `BundleDeployments` should happen on a timely fashion.

### Steps To Reproduce

1. Setup Rancher and at least 2 downstream clusters within the same cluster group.
2. In the `fleet-default` namespace (or where the downstream clusters were placed), add a new `GitRepo` that will deploy the same workload to all downstream clusters
   - Just anything should suffice, e.g. https://github.com/rancher/fleet-test-data/tree/master/simple
3. Wait for the `GitRepo` to become `Ready`, then observe the value that appears for `Resources` count and "ready clusters".
4. Edit the `GItRepo`'s targets configuration to only deploy to one downstream cluster.
5. Wait for `GitRepo` to become `Ready` again, then observe the `Resources` count and "ready clusters" didn't change.
6. After some time, this will eventually decrease to the desired value, meaning that `BundleDeployments` were effectively deleted.

### Environment

```markdown
- Fleet Version: 0.12
```

### Logs

```markdown

```

### Anything else?

I was uncertain of what process was actually deleting the `BundleDeployments` after a few minutes, thinking that it could be some scheduled or background job.
However, after some investigation I found that is only done from the `Cluster` reconciler, which not only triggers on their own events but also based on certain changes on `BundleDeployment` objects. This was causing the difference in behavior I observed.


Discussion:
@aruiz14: Regarding QA, in addition to the reproduction example in the description, the steps described here also apply: https://github.com/rancher/fleet/issues/2995#issuecomment-2785660659 @sbulage: ## System Information

### Before Upgrade:

| Rancher Version | Fleet Version |
|--------|--------|
| v2.11.0 | 106.1.0+up0.12.0 | 

### Steps followed
- Steps followed from: https://github.com/rancher/fleet/issues/3660#issuecomment-2858865335
- By creating `targetCustomization` with `doNotDeploy` options.
- `bundleDeployments` are taking too much time to remove.

---

### After Upgrade

| Rancher Version | Fleet Version |
|--------|--------|
| v2.11-9a013631ef611204d7812bc64b83771150aeb0d0-head | 106.1.1+up0.12.3-beta.1 |

- See video for dynamic removal of `bundleDeployments` with less than 5 seconds.
