fix: restore dead tutorial links via Wayback Machine

Replace 11 confirmed-dead README URLs from the link-rot report with verified
archive snapshots (or the live Hack Club workshops host), so entries stay in
the list instead of being removed.

Also restores Haskell Write You a Haskell and the Erlang chat app tutorial
to archived copies.

Fixes #900
Fixes #899
