Parent issue: #496
Depends on: torrust/torrust-index#294

After merging this PR on the backend we now have:

• Canonical infohashes
• A set of original infohashes sharing the same canonical infohash.

The relationship is one canonical infohash to many original infohashes.

We should:

• Rename the label # Info Hash in the action card to # Canonical Info Hash
• Add a new section like "Files" and "Trackers" named "Canonical Info Hash Group" with the list of all the uploaded torrent infohashes whose original infohashes generated the current torrent (canonical one).
• After uploading a new torrent, redirect to the URL (torrent details) with the canonical info-hash, not the original one. Although it also works because the backend redirects to the canonical one automatically.
