	 * Processes the block bindings and updates the block attributes with the values from the sources.

	 * A block might contain bindings in its attributes. Bindings are mappings
	 * between an attribute of the block and a source. A "source" is a function
	 * registered with `register_block_bindings_source()` that defines how to
	 * retrieve a value from outside the block, e.g. from post meta.
	 *
	 * This function will process those bindings and update the block's attributes
	 * with the values coming from the bindings.
	 *
	 * ### Example
	 *
	 * The "bindings" property for an Image block might look like this:
	 *
	 * ```json
	 * {
	 *   "metadata": {
	 *     "bindings": {
	 *       "title": {
	 *         "source": "core/post-meta",
	 *         "args": { "key": "text_custom_field" }
	 *       },
	 *       "url": {
