Fix: brand route on product brand (#1115)

#### What problem is this solving?

The `ProductBrand` component was returning a `brand` route with the `/b`
suffix, which should no longer be used. This was providing users with
access to a broken brand link. The solution was to remove the
incorrect/deprecated suffix.

#### How to test it?

1. Access a PDP ([example
PDP](https://vsseixaso--rougemaison.myvtex.com/vaso-la-majorelle-250-ml-h51131032/p))
2. Click on the brand displayed for the product (in this case, *Pip
Studio*)
3. The brand's PLP should load correctly ([example
PLP](https://vsseixaso--rougemaison.myvtex.com/pip-studio))
