Add Query Block Filtering by Taxonomies having non_queryable as false.

[Vedant-Gandhi]

What?

This PR allows the Query Block to be filtered with the taxonomies having non_queryable as false.

Why?

Reference Issue: #60301

How?

I have added an extra option to maintain backwards compatibility with the recent change introduced to disallow non-Queryable Taxonomies. My implementation follows a whitelisting approach where we can pass allowPubliclyQueryable to the useTaxonomies hook.

Testing Instructions

1. Ensure you have registered a custom taxonomy with non_queryable as false and bind it to your post type that will be used in the following step in Query Block.
2. Add a query loop block in the post.
3. Select the filters and go to taxonomies.
4. Ensure the custom taxonomy appears there.
