1. Corrected a typographical error in the `README.md` file, changing "registred" to "registered".
2. Updated the instruction text presented in the `product-collection-placeholder.tsx` file to offer clearer guidance for users.

- Updated the New Arrivals collection's default attributes to refine the block's appearance and content structure:
  - Reduced the default number of columns from 5 to 3
  - Set the default number of items per page to 9
  - Adjusted the collection attribute to reference the collection name dynamically
  - Replaced the hardcoded inner blocks template with a more dynamic structure, introducing a welcoming message and centralized product template usage
- Refactored constants.ts to create distinct inner block templates for product, pagination, and no-results scenarios, enhancing reusability across different collections and improving code readability with descriptive comments

Note:
The changes aim to streamline the New Arrivals collection setup and facilitate maintainability through a more dynamic and structured approach to inner block templates.

…onentProps and update props usage

- Renamed the `QueryEditComponentProps` type to `ProductCollectionEditComponentProps` to better match the Product Collection block context. Updated all occurrences in various files to maintain consistency.
- Changed `openPatternSelectionModalOpen` prop to `openPatternSelectionModal` to correct the typo and make the naming more intuitive. Updated its usage in different files accordingly.

…mments

- Renamed `QueryPlaceholder` component to `ProductCollectionPlaceholder` to better describe the component in the context of the Product Collection block.
- Adjusted the import statements to group WordPress dependencies together and highlighted a TypeScript expectation error regarding missing Gutenberg types with `@ts-expect-error`.

This commit introduces several improvements and refactors to the `product-collection` block:

- Utilized `block.json` for defining the block name in various files to centralize the block's configuration, making the codebase easier to maintain.
- Moved and renamed `PatternSelectionModal.tsx` file to streamline the file structure and reflect its usage accurately.
- Refactored the `PatternSelectionModal.tsx` file to:
   - Enhance type definitions and deal with missing TypeScript definitions using `@ts-expect-error`.
   - Update the import paths due to file relocations.
   - Streamline function names and parameters for better readability and understanding.
   - Change the modal title and category to reflect that users are choosing a "collection" rather than a "pattern".
- Improved `PatternSelectionModal` to use `block.json` name and category properties, promoting maintainability and adherence to DRY principle.
- Refactored `PatternSelectionModal` functions to construct the block query and apply it to patterns more robustly.
- Updated `product-collection-placeholder.tsx` to use block name from `block.json`.
- In `pattern-chooser-toolbar.tsx`, updated button label to indicate "Choose collection" instead of "Choose pattern" to maintain consistency with other changes.
- Removed redundant filter addition in `inspector-controls/index.tsx`.

1. Changes the title in the pattern selection modal from 'Choose a pattern' to 'Choose a collection'.
2. Updates the button text in the product collection placeholder from 'Add default Product Collection' to 'Use default collection'.

These changes aim to provide clearer instruction and terminology to the user.
