## Summary
* Rename the hyphenation update script to match the documented
`update_hyphenation.sh` name.
* Update the hyphenation trie documentation command example to use the
renamed script.
## Additional Context
The prose in `docs/hyphenation-trie-format.md` referred to
`update_hyphenation.sh`, but the command example and file on disk used
`update_hypenation.sh`. This made the documented script name
inconsistent with the runnable command.
Verified with `rg` that no references to the misspelled script name
remain. Also ran `bash -n scripts/update_hyphenation.sh` to syntax-check
the renamed script without downloading trie files.
