Pin libxml2 version to 2.13.7 (#2409)

This PR pins `libxml2` version to `2.13.7` due to libs dependency issue
with `2.14.0` version as reported on
[#146](conda-forge/libxml2-feedstock#146).

Without that change the conda package can not be build through GitHub
action, since `conda-build` raises error:
```python
