Hayoo.pm - add 'haskell map' to triggers (Issue #800)

Hello, since it's a really minor fix on an already existent instant answer I thought I didn't need to include the template; let me know if I must include it anyway.

I have tested the change as specified in CONTRIBUTING.md.
I'm not sure if "haskell map" should be a trigger -- if you're just trying to search Hackage for "map", all you need to search, given these triggers, is "hayoo map" or "haskell api map" E.g. https://duckduckgo.com/?q=hayoo+map

But with this as a trigger, you would need to search "haskell map <term>" -- is that what you intended?
