Bootstrap error with Composer 2

[serasset]

I just installed composer on my Mac, using brew (the composer installation from wp-react-starter failed).

Then launch create-wp-react-app create-workspace

The process goes on for a moment, then I get the following errors:

[...]

    - dealerdirect/phpcodesniffer-composer-installer v0.5.0 requires composer-plugin-api ^1.0 -> found composer-plugin-api[2.0.0] but it does not match the constraint.
  Problem 2
    - metasyntactical/composer-plugin-license-check is locked to version v0.5.0 and an update of this package was not requested.

You are using Composer 2, which some of your plugins seem to be incompatible with. Make sure you update your plugins or report a plugin-issue to ask them to support Composer 2.

I changed the version of 2 packages in my fork. This seems to make the trick.
