Replacing ubuntu-advantage-tools breaks update-manager

[chabala]

I have been using fake-ubuntu-advantage-tools with great success on 22.10, and have updated to the new version for 23.04.

I see now that the GUI update-manager tool has been broken by the replacement, and I suspect it acquired a dependency on ua-tools in 23.04:

$ /usr/bin/update-manager 
Traceback (most recent call last):
  File "/usr/bin/update-manager", line 38, in <module>
    from UpdateManager.UpdateManager import UpdateManager
  File "/usr/lib/python3/dist-packages/UpdateManager/UpdateManager.py", line 44, in <module>
    from uaclient.api.u.pro.packages.updates.v1 import updates
ModuleNotFoundError: No module named 'uaclient'

I have hacked this out, and all is working now, but perhaps fake-ubuntu-advantage-tools should manage this as well. Here's my sloppy hack:

<                     (info.package, info.version, info.download_size)
<                 )

Thanks for the patch! I confirmed this was necessary in 23.04 and added it to the instructions
