haskell: Update author name (#13268)

Pocæus created

I updated my Github username, and some bot is now parked at the old
username. I figured I should open a PR to update this.

Referring to the PRs (which show _this_ updated username):
https://github.com/zed-industries/zed/pull/6786,
https://github.com/zed-industries/zed/pull/6995,
https://github.com/zed-industries/zed/pull/7331.
