fix(contributors): count four people once, not twice

Four contributors appeared on the wall twice: once under their GitHub
login and once under the display name on commits whose email is not
linked to that account. The commit emails name the account in each
case:

- Horace Liu <im.liuhq@...>: liuhq
- Leo Douglas <douglarek@...>: douglarek
- maple <yekern@...>: yekern
- Alexander Kireev <ak.chatman.media@...>: chatman-media

They are added to unlinked_aliases, mapping each name to its login. The
render step drops an unlinked name that matches a login, so each person
now has one tile. After `scripts/contributor-wall.py refresh` and
`render`: 390 accounts plus 27 unlinked names, 417 people (from 421).

Found by the final review of the Hangzhou deck, whose thank-you slide is
built from this file.
