HTML Reporter: Fix broken "Rerun without a depth limit" link (really)

Krinkle · Krinkle · commit 73c03cf27745 · 2024-12-05T20:28:20.000Z
Follows-up 91db92d, which recently fixed another part of the `maxDepth` feature, but left the HTML still invalid. Follows-up 47e3b99, which broke the HTML by mistakenly swapping one of the double quotes for a single quote, thus leaving the anchor element unclosed.
