Correction to SAI to re-implement RP text for quest 9066 (Swift Discipline)

Originally corrected here https://github.com/TrinityCore/TrinityCore/issues/11118
Undone here https://github.com/TrinityCore/TrinityCore/commit/336885480d84313eda0514b97105d25965453f95

This change keeps changes made in the second commit, but re-adds the link and the second line to send text.

In theory it should work on 4.3.4 too (and eventually 6.x). But, I don't have a setup to test it.
