Use 'main-dev' branch for Next Major to enable D12 testing
Problem/Motivation
Core started using "main" as announced here: https://www.drupal.org/about/core/blog/introducing-the-main-branch-for-drupal-core
We have a few references to 11.x in the docs and the code.
Check which ones need changing and which ones don't.
Proposed resolution
- Use 'main' as the core branch that is used in the Next Major variant, because this branch contains
const VERSION = 12.0-dev - Leave the Next Minor variant to use 11.x, as this is using
const VERSION = 11.4-dev
