Fix syntax warning when using Python 3.12. (#7022)

Browse source 
This happens when generating the Python API and you are using
Python 3.12 in the build environment:

```
.../z3/scripts/update_api.py:1828: SyntaxWarning: invalid escape sequence '\#'
```

This was a `DeprecationWarning` previously, but Python 3.12 changed
it to a `SyntaxWarning` to make it more visible. The release notes
indicate that this will be a syntax error in the future.
