Licenses `AGPL-3.0-only` and `AGPL-3.0-or-later` link to the same page

Right now URL https://www.gnu.org/licenses/agpl.txt redirects to https://www.gnu.org/licenses/agpl-3.0.txt, which is the latest version of the license at the time of writing. Greasy Fork pages of scripts with SPDX identifiers AGPL-3.0-only and AGPL-3.0-or-later for the @license meta key are linked to https://www.gnu.org/licenses/agpl.txt. This is fine now, but will break in the future, if AGPL-3.1 or AGPL-4.0 are ever released.

Examples of affected scripts:

• AGPL-3.0-only: https://greasyfork.org/en/scripts/473195-git-copy-commit-reference
• AGPL-3.0-or-later: https://greasyfork.org/en/scripts/460549-pt-helper

Notes

• I managed to find SQL patch db/migrate/20140517032450_insert_initial_licenses.rb, but I couldn't figure out how AGPL was added to the database table.
• Corresponding pages on the SPDX website:
  • https://spdx.org/licenses/AGPL-3.0-only.html
  • https://spdx.org/licenses/AGPL-3.0-or-later.html

Greasy Fork got its license data from https://raw.githubusercontent.com/spdx/license-list-data/master/json/licenses.json and parsed it with this task.

Greasy Fork was using the first "see also" URL, but I've updated it to use the SPDX page, so I think that solves your concern. Should the data change in the future, I'd just have to run the task again.

The AGPL links on the website now look good to me. Thanks!
