Problem/Motivation
in #3085717: [PP-1] Do not rely on version_* tags it was determined that release information version_patch and version_extra are not fully tested.
In that issue we want to remove reliance on this metadata from the update xml and instead get the information directly from version number instead.
We should first make sure we have test coverage for the current functionality. Currently these are taken into account for contrib test and may be under tested for core
Proposed resolution
Determine what test coverage we are missing and create it
Remaining tasks
Duplicate \Drupal\Tests\update\Functional\UpdateCoreTest::testNormalUpdateAvailable() which test version_patch and version_extra for core in \Drupal\Tests\update\Functional\UpdateContribTest for contrib
