Revert "lava: Drop a bunch of spurious `name:` keys"

This reverts commit 9dc1fafa.

Revert this changes since QA Report App tries to use this metadata and currently rises the following exception:

File "/app/testobjects.py", line 143, in lava_jobdata_extract_results
  t['group'] = testgroup['name']
KeyError: 'name'

This causes tests results for v2023pre not being processed.

It is not clear if this metadata is used, however, currently it is not possible to easily deploy a new version of QA Report app, so the best approach is to revert this change.
