Scripts: Add BlueOak-1.0.0 license to GPL2 compatible (#66139)

- Add BlueOak-1.0.0 to GPLv2 compatible licenses recognized by
  wp-scripts check-licenses.
- Remove redundant ignores from Gutenberg's check-licenses script.

This license appears on some npm packages. It's intended to be highly
permissive. The website states that it should be GPLv2 compatible:

> Is the model license compatible with GPL?
>
> The Council doesn’t see any reason why software licensed under the
> Blue Oak Model License 1.0.0 can’t be used, combined, and distributed
> with software under GPLv2, LGPLv2.1, GPLv3, LGPLv3, or AGPLv3.
