Use of temporary attributes causes edits to block templates

### Description of the bug

The query block's `Edit` component relies on setting attributes that aren't defined by `block.json` and so aren't serialized with the block, including `validPosts`, `query`, and `queryId`.

When a query block appears in a block theme's template files and the template is rendered in the editor while editing a post, these attributes are set, causing the editor to report that the site's template files have been updated and need to be saved.

### Steps To Reproduce

1. Add a query block to a block theme template or template part.
2. Edit a post and select "Show template" from the preview dropdown menu.
3. Observe that the save button becomes enabled and prompts you to save changes to the block template.
