Add manifests to the published releases

[maxgio92]

Feature

Release both binaries and operator manifests (CRDs, webhook configurations, controller, RBAC, etc.).

Motivation

Consumers might need or want to install Kamaji from bare manifests, without the requirement of using Helm.

Additional context

A practical scenario can be kamajictl which can install a specific version of Kamaji, by downloading and applying its released manifests.

Goreleaser could then be leveraged to bundle in the release archive binaries, manifests, signatures, etc. (e.g. https://github.com/fluxcd/kustomize-controller/blob/main/.goreleaser.yaml#L6).

I try to use go releaser to build the program, this is my rendering, does it meet the requirements?

I changed the architecture of the program build.
