just out of curiosity and history: why this change? @shayancanonical

It's related to the pytest-asyncio update that I'd tried to fix on dpw But, in details:

• systems with python 3.12 (noble) pulled pytest-asyncio-0.27.3 on poetry update
• pytest-asyncio-0.27.3 has the bug that duplicates all pytest markers
  • pytest-asyncio add a asyncio to all async def test... when configure to auto mode, which saves the hassle of adding the mark to every test function manually
• duplicated group marker is breaking an assertion on test collection step on dpw groups plugins (hence the temptive fix on it)
• when testing the fix on dpw, tests are stuck on initial tests. Local tests showed that downgrading only pytest-asyncio fix the issue, so there's more issues in it then the markers duplication
