RFR: 8351332: Line breaks in search tag descriptions corrupt JSON search index

Mon Mar 24 14:55:50 UTC 2025

Please review this patch to fix an issue in the `tag-search-index.js` generation.

The problem was in the `toJSON()` method of `IndexItem`. When adding the description, it's using `escapeQuotes(description)` which only escapes backslashes and quotes, but doesn't normalize whitespace.

TIA
