Emoji that we specifically choose names or aliases for will be
stored in this new file so that we can generate emoji_names.py
from the custom names and also CLDR (for the rest).
This new file isn't used for anything yet (no user facing change);
it will be used in future commits.
This tool helps catch common typos in code and documentation, which is
particularly useful for our many contributors who are not native
English speakers.
The config is based on the codespell that I ran in
https://github.com/zulip/zulip/pull/18535.
