[collector] Add kubernetesObjects preset for k8sobjects receiver (#2196)

* [collector] Add kubernetesObjects preset for k8sobjects receiver

Add a new preset that configures the k8sobjects receiver to collect
Kubernetes objects as logs, with grouped resource categories and
configurable collection modes.

The preset supports:
- Collection modes: pull, watch, or pullWatch
- Configurable pull interval (defaults to receiver default)
- Resource groups: core (enabled by default), rbac, storage,
  networking, autoscaling, policy, apiExtensions
- Extra resources escape hatch for custom resources
- Full compatibility with existing kubernetesEvents preset
  (objects lists are merged when both are enabled)

* fix vpa

* remove mode, pullInterval and extraResources options

* use default pull interval value

* update comments

* bump the chart and regenerate the example

* support  leader election

* add new ci test files

* add option watch

* bump the chart and regenerate the example

* add an example
