Consider changing the minimum-stability to stable

[alexpott]

The drupal/recommended-project composer project template recently had a bug that meant running composer update resulted in get a dev core release. See https://www.drupal.org/project/drupal/issues/3135247 and composer/composer#8882

This same problem could hit the thunder project. We should consider removing the minimum-stability flag from the template.

Doing this at the moment results in:

  Problem 1
    - thunder/thunder-distribution 3.4.5 requires drupal/access_unpublished ^1.0-alpha8 -> satisfiable by drupal/access_unpublished[1.x-dev, 1.0.0-alpha8, 1.0.0-beta1, 1.0.0-beta2] but these conflict with your requirements or minimum-stability.
    - thunder/thunder-distribution 3.4.4 requires drupal/access_unpublished ^1.0-alpha8 -> satisfiable by drupal/access_unpublished[1.x-dev, 1.0.0-alpha8, 1.0.0-beta1, 1.0.0-beta2] but these conflict with your requirements or minimum-stability.
    - thunder/thunder-distribution 3.4.3 requires drupal/access_unpublished ^1.0-alpha8 -> satisfiable by drupal/access_unpublished[1.x-dev, 1.0.0-alpha8, 1.0.0-beta1, 1.0.0-beta2] but these conflict with your requirements or minimum-stability.
    - thunder/thunder-distribution 3.4.2 requires drupal/access_unpublished ^1.0-alpha8 -> satisfiable by drupal/access_unpublished[1.x-dev, 1.0.0-alpha8, 1.0.0-beta1, 1.0.0-beta2] but these conflict with your requirements or minimum-stability.
    - thunder/thunder-distribution 3.4.1 requires drupal/access_unpublished ^1.0-alpha8 -> satisfiable by drupal/access_unpublished[1.x-dev, 1.0.0-alpha8, 1.0.0-beta1, 1.0.0-beta2] but these conflict with your requirements or minimum-stability.
    - thunder/thunder-distribution 3.4.0 requires drupal/access_unpublished ^1.0-alpha8 -> satisfiable by drupal/access_unpublished[1.x-dev, 1.0.0-alpha8, 1.0.0-beta1, 1.0.0-beta2] but these conflict with your requirements or minimum-stability.
    - Installation request for thunder/thunder-distribution ~3.4 -> satisfiable by thunder/thunder-distribution[3.4.0, 3.4.1, 3.4.2, 3.4.3, 3.4.4, 3.4.5].

At the moment the thunder-distribution is relying on the top-level composer.json minimum-stability to allow installation.

We need to add stability flags for all of these modules:

drupal/access_unpublished                       1.0.0-beta2   Grants access to view unpublished content to anyone who has a unique URL and appropriate permissions.
