* (fix): Fix Docker builds failing when projects don’t include apis/, controllers/, or webhooks by updating .dockerignore to allow only Go source files and module metadata

The make docker-build command no longer fails for new projects that don't yet have api/ or internal/ directories.

- The .dockerignore file has been updated to filter the build context, ensuring only necessary files are included.

* (docs) drop patchStrategy/protobuf tags from Conditions in Getting Started section

Followup of PR #4893

These tags are of no use for CRDs. They have their use
in k8s core types in order to produce proper strategic merge patches, see
https://github.com/kubernetes/community/blob/master/contributors/devel/sig-api-machinery/strategic-merge-patch.md
but are superseded by +listType and +listMapKey in CRD world.

Added `+listType`, `+listMapKey` and `+optional` markers to the example snippet
