Add pipeline task approve logic

[callmevladik]

This task aims to implement approval functionality within the Portal UI, enabling users to Approve or Reject approval tasks directly from the interface. This functionality is critical for streamlining the approval process in our deployment pipelines, particularly when using Tekton pipelines with custom tasks for deployment approvals.

{}Pre-requisites{}:

Deploy the environment with the latest Tekton pipeline using the 'deploy-with-approve' deployment template.

{}Technical Details{}:

1. It is essential to identify custom Tasks in the Tekton Pipeline, distinguishing between traditional and custom tasks based on their 'taskRef' properties.
2. The Portal UI should display "Approve" and "Reject" buttons for identified custom tasks. The exact location of these buttons within the UI needs discussion and finalization.
3. Upon user interaction (Approve/Reject), the Portal UI should modify the corresponding custom resource 'ApprovalTask' to reflect the user's decision. This modification is based on identifying the 'ApprovalTask' resource using labels.
4. The status and visual presentation of the approval task within the UI should derive from the 'CustomRun' resource, identifiable through labels or owner references. States of task https://github.com/KubeRocketCI/tekton-custom-task/blob/main/deploy-templates/crds/edp.epam.com_approvaltasks.yaml

spec.action set to: Approved/Rejected

{}Acceptance Criteria{}

1. The Portal UI successfully identifies custom tasks within Tekton Pipelines, specifically those marked as 'ApprovalTask'.
2. "Approve" and "Reject" buttons are correctly displayed within the Portal UI for each identified custom task.
3. User interactions with the "Approve" or "Reject" buttons appropriately modify the 'ApprovalTask' custom resource to reflect the chosen action.
4. The visual presentation and status of approval tasks within the Portal UI accurately reflect the current state of the task, derived from the 'CustomRun' resource.
5. Comprehensive documentation is provided detailing the implementation process, user interaction flow, and any necessary configuration steps.
