404 not found wiki.apache.org/jakarta-lucene links not forwarded to lucene-java [LUCENE-7819]

Links with http://wiki.apache.org/jakarta-lucene/... are currently not being forwarded, and instead result in a plain 404 Not Found page.

Apparently they should be forwarded to http://wiki.apache.org/lucene-java/... since bug #1866 changed the path, and were being forwarded at that time.

Links that still contain 'jakarta-lucene' include links from JavaDoc and links from the wiki.apache.org top page.

To Reproduce:
Click on one of the jakarta-lucene URLs below.
Actual Result: 404 Not Found page
Expected Result: forwarded to corresponding lucene-java page.

Examples
http://lucene.apache.org/core/6_5_1/suggest/org/apache/lucene/search/spell/package-summary.html
links to http://wiki.apache.org/jakarta-lucene/SpellChecker

https://wiki.apache.org/general/
links to http://wiki.apache.org/jakarta-lucene/FrontPage
and to http://wiki.apache.org/jakarta-lucene/lucene.Net

Start by checking the example jakarta-lucene URLs and compare them with the corresponding lucene-java destinations, then read bug #1866 for the historical path change. No repository file or test is named; the work is done when the listed jakarta-lucene links, including JavaDoc and wiki links, redirect to the matching lucene-java pages instead of returning 404.
