"mlp infection" and "infection au" should be merged

mlp infection < - > infection au

Both describe the “infection AUs” that have been popular on certain platforms lately. “mlp infection” has many more images under the tag, but as someone who doesn’t interact too much with it, “infection au” feels like the better name. I don’t know. Perhaps the tag could use a description too?

edit: maybe there’s some that technically aren’t alternate universes? in which case go with “mlp infection”
