List of Go Kata to Update

The following kata needs manual update to enable Go 1.18. Any help is appreciated.

1. Error correction #1 - Hamming Code
2. IP Validation
3. Longest Common Subsequence
4. Playing with passphrases
5. Tank Truck

Use the new "Fork" feature to update kata:

You don't need to open an issue/suggestion and wait to edit. Forking a kata in a language is similar to forking an approved translation, but better because

• all languages can be forked, including those added directly in Kata Editor and the original language
• it's never outdated because it forks from the kata

You should see "Fork" when viewing a kata with the language you've completed in selected. Click that to open a translation editor with the current version filled in. The proposed changes can be merged or rejected after publishing, just like translations.
