chore: Update to the new version of brand-openedx in the new scope. (#585)

Part of https://github.com/openedx/axim-engineering/issues/23

This updates the `@edx/brand` alias to point to the `brand-openedx` package at
the `openedx` scope. This does not impact imports because this package is used
via an alias.
