fix: update flux api version CR

[frewilhelm]

Flux deprecated their CR source.toolkit.fluxcd.io/v1beta2. Now source.toolkit.fluxcd.io/v1 is required.

@frewilhelm the e2e tests fail. I guess this change need to be propagetd through multiple places:

=== RUN   TestHelmChartResource/Configure_Management_Repository
Handling connection for 3000
    helm_test.go:82: successfully created repository at url http://localhost:3000/e2e-tester/ocm-controller-helm-test.git
    helm_test.go:82: Created token secret flux-system/ocm-controller-helm-test
    helm_test.go:82: no matches for kind "GitRepository" in version "source.toolkit.fluxcd.io/v1beta2"

[frewilhelm]

This is still failing. I need to check it locally. Probably need to push some changes to another repository

Didn't check the e2e test results

[frewilhelm]

ocm-e2e-framework imports an old version from flux. I think I might update this to make it work

Got it.

PASS
ok      github.com/open-component-model/ocm-controller/e2e      232.229s

DONE 65 tests in 232.234s

I'll push in a second.
