	 * Registers a new block bindings source.
	 *
	 * This is a low-level method. For most use cases, it is recommended to use
	 * the `register_block_bindings_source()` function instead.
	 *
	 * @see register_block_bindings_source()
	 *
	 * Sources are used to override block&#039;s original attributes with a value
	 * coming from the source. Once a source is registered, it can be used by a
	 * block by setting its `metadata.bindings` attribute to a value that refers
	 * to the source.
	 *
	 * @since 6.5.0
	 *
	 * @param string $source_name       The name of the source. It must be a string containing a namespace prefix, i.e.
	 *                                  `my-plugin/my-custom-source`. It must only contain lowercase alphanumeric
	 *                                  characters, the forward slash `/` and dashes.
	 * @param array  $source_properties {
	 *     The array of arguments that are used to register a source.
	 *
	 *     @type string   $label              The label of the source.
	 *     @type callable $get_value_callback A callback executed when the source is processed during block rendering.
	 *                                        The callback should have the following signature:
	 *
	 *                                        `function( $source_args, $block_instance, $attribute_name ): mixed`
	 *                                            - @param array    $source_args    Array containing source arguments
	 *                                                                              used to look up the override value,
	 *                                                                              i.e. {&quot;key&quot;: &quot;foo&quot;}.
	 *                                            - @param WP_Block $block_instance The block instance.
	 *                                            - @param string   $attribute_name The name of the target attribute.
	 *                                        The callback has a mixed return type; it may return a string to override
	 *                                        the block&#039;s original value, null, false to remove an attribute, etc.
	 *     @type string[] $uses_context       Optional. Array of values to add to block `uses_context` needed by the source.
	 * }
	 * @return WP_Block_Bindings_Source|false Source when the registration was successful, or `false` on failure.
