Using * in registerBlockExtension throws namespace validation error

[palicko]

Describe the bug

Hey,
when * is used in registerBlockExtension() to target all blocks, WP throws validation error:

hooks.js The namespace can only contain numbers, letters, dashes, periods, underscores and slashes.

Steps to Reproduce

Register new block extension with *, e.g.:

registerBlockExtension('*', {
  extensionName: 'demo/addExtension',
  attributes: {},
  inlineStyleGenerator: () => {},
  classNameGenerator: () => {},
  order: 'before',
  Edit: () => <></>,
});
