ERROR: ModuleNotFoundError: No module named 'urwid.decoration'

Seems like [urwid v4.0.0](https://github.com/urwid/urwid/releases/tag/4.0.0) broke `bzt`:

> ERROR: ModuleNotFoundError: No module named 'urwid.decoration'



> Requirement already satisfied: urwid>=3.0.2 in /opt/actions-runner/_work/_tool/Python/3.11.15/x64/lib/python3.11/site-packages (from bzt) (4.0.0)

Should probably define the requirement as this instead:

```
urwid~=3.0.2
```
