_content/doc: remove second extra < in HTML

Commit 18b7f5b1d41 from last week, updated the release notes for 1.19 and
1.20 which included a copy/paste HTML formatting error, fixing the second
place here. Also verified these were the only two places in website that got
this typo. The comment version of this in go repo is not HTML formatted, so
no typo.

Typo from an update last week, remove an second extra '<'.

Updates golang/go#59534
