Revert "Enable Sentry asyncio integration (#5685)" (#5729)

This essentially reverts PR #5685.

The Sentry `AsyncioIntegration` replaces the asyncio task factory with
its instrumentalized version, which reports all execeptions which
aren't handled *within* a task to Sentry.

However, we quite often run tasks and handle exceptions outside, e.g.
this commen pattern (example from `MountManager` `reload()``):

```python
results = await asyncio.gather(
    *[mount.update() for mount in mounts], return_exceptions=True
)
... create resolution issues from results with exceptions ...
```

Here, asyncio.gather() uses ensure_future(), which converts the
co-routines to tasks. These Sentry instrumented tasks will then report
exceptions to Sentry, even though we handle exceptions gracefully.

So the `AsyncioIntegration` doesn't work for our use case, and causes
unnecessary noise in Sentry. Disable it again.
