PR Summary

• Addition of a New Unit Test Class
  A new unit test class named Test_Rsvp_Template has been added. This will help in conducting unit tests for the Rsvp_Template block under GatherPress\Core\Blocks, ensuring the robustness and reliability of the block.

• Implementation of the test_setup_hooks Method
  This PR implements the method test_setup_hooks. This method is designed to confirm the correct filters are registered during the initialization of the RSVP Template block. This check ensures the block behaves as expected.

• Definitions of Checking Hooks
  The PR also defines hooks to ensure methods ensure_block_styles_loaded and generate_rsvp_template_block are properly integrated into the render block filter. This step ensures the block loads the required styles and generates the RSVP template block correctly.
