Canonical tags are incorrect

[excentrickristy]

During a recent crawl of the site I realized that the canonical URLs are being set incorrectly in the tutorial section of the website.

You can see here what the actual page url is vs the canoncial being set in the code:

This is the code in the template:
<link rel="canonical" href="https://jakarta.ee/learn/docs/jakartaee-tutorial/current/index.html/jakartaee-tutorial/current/index.html">

it looks like maybe a variable is being repeated here that shouldn't be. This is the case on all of the tutorial pages. If we can get this fixed it will help improve search indexing.
