Is your feature request related to a problem? Please describe.

Currently, the tekton-lint tool does not properly handle parameters of type object in Tekton pipeline definitions. This causes issues when parameters of this type are used in tasks, resulting in incorrect warnings and errors.

For example, given a parameter defined as:

- name: gitRepository
  description: Git Repository.
  type: object
  properties:
    defaultBranch:
      type: string
    name:
      type: string
    owner:
      type: string

And its usage in a task:

- name: repositoryName
  value: $(params.gitRepository.name)

The tool incorrectly reports:

Undefined param 'gitRepository.name' at .spec.tasks[2].params[8].value in 'git-clone'

Describe the solution you'd like
The tool should correctly recognize and handle parameters of type object and their properties, without reporting them as undefined.

Describe alternatives you've considered
