[Bug]: flux_bootstrap_git destroy should align with the behavior of flux uninstall

[debaprita]

Describe the bug

Behavior of flux uninstall removes all the CRDs and necessary finalizers from the cluster. However, executing destroy with the Flux Terraform provider causes HelmRelease CRD to get stuck in a Terminating state. It is imperative to run flux uninstall to ensure proper cleanup, including their finalizers. There are helm.toolkit.fluxcd.io/v2beta1 HelmRelease objects defined on the cluster.

Status of HelmRelease CRD after running terraform destroy:

status:
  acceptedNames:
    kind: HelmRelease
    listKind: HelmReleaseList
    plural: helmreleases
    shortNames:
    - hr
    singular: helmrelease
  conditions:
  - lastTransitionTime: "2024-09-29T16:48:09Z"

    message: CustomResource deletion is in progress
    reason: InstanceDeletionInProgress
    status: "True"
    type: Terminating
  storedVersions:
  - v2

Steps to reproduce

1. terraform apply to install flux on AKS cluster
2. flux installed successfully
3. terrform destroy to uninstall flux
4. kubectl get crds | grep flux helmreleases.helm.toolkit.fluxcd.io
5. flux uninstall --namespace=flux-system --keep-namespace Are you sure you want to delete Flux and its custom resource definitions: y ► deleting components in flux-system namespace ► deleting toolkit.fluxcd.io finalizers in all namespaces ✔ HelmRelease/ingress-nginx/ingress-nginx finalizers deleted ✔ HelmRelease/monitoring/prometheus finalizers deleted ► deleting toolkit.fluxcd.io custom resource definitions ✗ CustomResourceDefinition/helmreleases.helm.toolkit.fluxcd.io deletion failed: customresourcedefinitions.apiextensions.k8s.io "helmreleases.helm.toolkit.fluxcd.io" not found ✔ uninstall finished
6. kubectl get crds | grep flux now returns nothing

Expected behavior

Running terraform destroy should have deleted HelmRelease CRD and its finalizers.

Thanks for submitting the bug. I'll take a look at it this week.

[swade1987]

I wanted to provide a quick update on my availability as a maintainer. I pride myself on transparency and realise my standards have slipped in the last few months.

Since starting a full-time role in September, I have significantly less time to dedicate to this project. I'm now working on issues and pull requests out of hours on a best-effort basis.

Please bear with me if I take longer than usual to respond or review. I remain committed to the project and appreciate your patience and understanding during this transition.

Thank you for your continued support and contributions. I want you to know I'm committed to maintaining better communication.
