function update_verify_update_archive in Drupal 10

Same name and namespace in other branches

1. 8 core/modules/update/update.module \update_verify_update_archive()
2. 7 modules/update/update.module \update_verify_update_archive()
3. 9 core/modules/update/update.module \update_verify_update_archive()

Implements hook_verify_update_archive().

First, we ensure that the archive isn't a copy of Drupal core, which the update manager does not yet support. See https://www.drupal.org/node/606592.

Then, we make sure that at least one module included in the archive file has an .info.yml file which claims that the code is compatible with the current version of Drupal core.
