Update tooling

[bojand]

Changes

Updates controller gen tool to version 0.15.0. With go 1.22.2 and 1.22.3 I was getting crash when generating code. It seems related to either kubernetes-sigs/controller-tools#880 or kubernetes-sigs/controller-tools#851. If I use to go version 1.21.10 it seems to work. Or if I update to version 0.14.0 or 0.15.0 of controller gen. This did change the YAML formatting of the manifests.

Updates testcontainers and redpanda module to version 0.29.1. This was needed due to some fixes for better support of non-Docker container runtimes like Podman and Rancher Desktop. Particularly there were fixes in the Redpanda module as well to improve support for these.
The version picked is due to testcontainers/testcontainers-go#2477 which causes issues with using 0.30.0 version.
As a result of updating testcontainers I needed to update oras.land/oras-go for some reason, as I was getting the following errors:

❯ ./task k8s:run-unit-tests
task: [k8s:run-go-vet] go vet ./...

# oras.land/oras-go/pkg/auth/docker
../../../../../go/pkg/mod/oras.land/oras-go@v1.2.4/pkg/auth/docker/login_tls.go:44:20: undefined: types.AuthConfig
../../../../../go/pkg/mod/oras.land/oras-go@v1.2.4/pkg/auth/docker/login_tls.go:62:131: undefined: types.AuthConfig

../../../../../go/pkg/mod/oras.land/oras-go@v1.2.4/pkg/auth/docker/login.go:54:16: undefined: types.AuthConfig
exit status 1

Now k8s:run-unit-tests passes locally for me.
