feat(stackable-versioned)!: Integrate with ConversionReviews (#1050)

* feat(stackable-versioned): Add flux-converter

* test: Add roundtrip generation via macro

* fix some tests

* Fix remaining tests

* fix rest of tests

* refactor(k8s-version): Move darling code into module

* refactor(stackable-versioned): Split utils into separate files

* chore(stackable-versioned): Cleanup, move and improve conversion code

* chore(stackable-versioned): Move K8s related error enums

* chore(stackable-versioned): Move code, add error handling

* chore(stackable-versioned): Remove roundtrip tests

These tests are removed for now, because we are not able
to roundtrip CRD conversions without data loss yet. This
feature will be re-added in a follow-up PR in an improved
form once loss-less roundtripping is supported.

* chore(crd-preview): Fix macro, add re-exports

* chore!(stackable-versioned): Remove unused merged_crd skip flag

* fix(stackable-versioned): Emit status field during conversion

* chore: Fix clippy lints

* test(stackable-versioned): Adjust snapshots

* chore: Add rust-analyzer setting

* chore: Allow RUSTSEC-2024-0436 advisory

* chore(stackable-versioned): Remove unused fixtures

* chore(stackable-versioned): Remove unused feature

* chore(stackable-versioned): Fix rustdoc

* chore: Remove unused dependencies

* chore(stackable-versioned): Move Otel attributes into constants

* docs(stackable-versioned): Adjust K8s doc comments

* test(stackable-versioned): Improve conversion_paths unit test

* chore(stackable-versioned): Update changelog

* chore: Apply suggestions
