autodoc: failed to import function 'trim_conandata' from module 'conan.tools.files.conandata'

### Problem Description

I tried to build the documentation of `release/2.0` branch. The following commands are the demo:

```
git clone https://github.com/conan-io/docs.git
cd docs
git checkout release/2.0
pip install -r requirements.txt
make html
```

However, the error showed up:
