Fix the links on the doc page for the 0.291 release

[dnskr]

Description

Fix the incorrect links on the 0.291 release page:

1. The upgrade notes of lucene-core, lucene-queryparser and lucene-analyzer-common should have the same link to WS-2021-0646. Actually, changed link https://vuln.whitesourcesoftware.com/vulnerability/WS-2021-0646 redirects to https://www.mend.io/vulnerability-database/WS-2021-0646 page.
2. The upgrade note of hibernate-validator has link with incorrect PR number (24168 instead of 24177).
