Promotional is usually short for "promotional offers" which are often tied to "promotional events". In the context of World of Warcraft, these offers or events are usually sponsored or co-sponsored by Blizzard with or without a partner.
These offers or events are called promotional, because they are part of a marketing campaign to promote some brand, idea or product.
