Add docs for CreateEscalation and WaitEscalation interrupt models

[Copilot]

CreateEscalation and WaitEscalation were missing from the Human-In-The-Loop documentation despite being exported from uipath.platform.common and used in escalation workflows.

Changes

• docs/human_in_the_loop.md: Added sections 3 (CreateEscalation) and 4 (WaitEscalation), renumbered InvokeProcess → 5 and WaitJob → 6
  • CreateEscalation — escalation-specific subclass of CreateTask; same attributes, documents the agent-to-human escalation workflow variant
  • WaitEscalation — escalation-specific subclass of WaitTask; takes action: Task (the already-created escalation task), app_folder_path, and app_name

# Create and wait for an escalation in one step
from uipath.platform.common import CreateEscalation
escalation_output = interrupt(CreateEscalation(
    app_name="AppName",
    app_folder_path="MyFolderPath",
    title="Escalate Issue",
    data={"key": "value"},
    assignee="user@example.com"
))

# Wait for an already-created escalation task
from uipath.platform.common import WaitEscalation
escalation_output = interrupt(WaitEscalation(
    action=my_task_instance,
    app_folder_path="MyFolderPath"
))
