Ensure Shop Page Uses Block Renderer When Applicable (#44453)

[Lee-WonJun]

Changes proposed in this Pull Request:

Implemented an update to prioritize block rendering for the Shop page with filter queries, adjusting the template selection to favor 'archive-product' block templates. Note: The impact on other taxonomies has not been fully explored; caution is advised.

Closes #44453 .

How to test the changes in this Pull Request:

• Navigate to a WordPress environment with WooCommerce installed and activated.
• Ensure that a block template for 'archive-product' is available and activated.
• Visit the Shop page without applying the patch, noting the rendering inconsistency when the product lookup table is not used.
• Apply the patch and refresh the Shop page. The Block UI should now render correctly, demonstrating that the Shop page is utilizing the block renderer.
• Disable the block template for 'archive-product' and verify that the fallback behavior remains intact, with the appropriate template being loaded for product attributes, categories, and tags.

Hi, I need some guidance for testing this:

Ensure that a block template for 'archive-product' is available and activated.

How can I achieve this? Is it enough to install a block theme like e.g. Blockbase?

Yes, any block theme has archive-product.html
for you, tested themes are Blockskit Shop / deco (not free) / Gadgethub

@Lee-WonJun as I mentioned in the issue, thank you a lot for filling this bug and investigating it. It turns out, the bug was fixed in #44537 as we refactored some code and the fix will ship in WooCommerce 8.8.

In #44850, I also implemented some changes that should make it harder for this kind of issues to appear in the future.

Based on that, I will go ahead closing your PR. Hope that makes sense! And once again, thanks for your time helping us solve this bug.
