No longer try to import __version__ from release.py. (#16817)

I'm not sure why that would be desirable -- we really want __version__
to come from the controller whereas importing will come from the client
node.  If it turns out there was a reason to do that, please be sure to
use an exception handler that catches all exceptions instead of only
catching ImportError:

```
try:
    from ansible.release import __version__, __author__
except:
    __version__ = [...]
```

Fixes #16523
