docs(search): correct edit distance example

[IvoCrnkovic]

Summary

• Correct the edit-distance example using jovscript to javascripts, which takes the three listed edits.
• Show each intermediate spelling so the substitution and two insertions are easy to verify.

Verification

• Confirmed the minimum edit distance is 3 with a Levenshtein-distance check.
• npm run lint
• npm test (449 passed)
• npm run docs:build
