Twig macro documentation link goes to Twig 1.x docs

Problem/Motivation

Several templates (such as menu.html.twig) use a twig macro, and include a link to Twig docs for more info about the macro tag.

This Twig docs link goes to Twig 1.x docs:
https://twig.symfony.com/doc/1.x/tags/macro.html

Drupal 10 uses Twig 3.x, so let's update that link!
https://twig.symfony.com/doc/3.x/tags/macro.html

(...or remove it! -- see Proposed resolution)

NOTE: There are a few instances of menu.html.twig with the 1.x docs link (system module template, and many/all the overrides of menu.html.twig provided by themes that come with Drupal core). (menu.html.twig is just one example)

Steps to reproduce

Again, using menu.html.twig as reference: Look at any instance of menu.html.twig in the Drupal project. For example:
core/modules/system/templates/menu.html.twig

Proposed resolution

Option 1

Update the link wherever it exists! -- NOTE: The 1.x link is not broken, and there's a link to the 2.x and 3.x docs on the 1.x docs (though it doesn't take you directly to the macro documentation, just the homepage for each major version's docs). In other words, this outdated link situation is not an emergency.

Option 2

Remove the link...? -- we've been on Twig 2.x for a while and no one's created an issue (!! that I found, important caveat !!), maybe that means no one uses this link?

Remaining tasks

Let's be extra clear/methodical with this low-priority novice issue.

1. Seek guidance on replacing vs. removing this link (i.e. on Drupal Slack > #contribute channel, unless someone comments right on this issue thread).
2. Track down all instances (i.e. on a clean copy of Drupal 10, grep for the 1.x macro documentation URL). Optionally, add the list of instances to this issue summary.
3. Change all those instances (replace or remove, based on decision in step 1).
