This PR adds regression test data for webhook operator bundle conversion functionality. It introduces a new test case that validates the rendering of a webhook operator bundle (v0.0.5) containing all types of webhooks: conversion webhooks, mutating admission webhooks, and validating admission webhooks.

Key Changes:
