Respect `VERSIONS` file in typeshed

### Describe the Bug

Typeshed contains a [`VERSIONS` file](https://github.com/python/typeshed/blob/main/stdlib/VERSIONS) indicating stdlib modules' version availability. For example, the `distutils` package is only available from Python 3.0 to 3.11, so importing it in Python 3.12+ is considered an error that gets reported by all of mypy, pyright, and ty:
```python
import distutils # Should be an error in python 3.12+, but pyrefly is silent
```
Pyrefly probably needs to include this `VERSIONS` file into its bundled typeshed, and adjust what `BundledTypeshed` contains dynamically based on the python version.
