docs: github doc build fails in package lxml

In github actions for building the docs, while installing the
dependancies from requirements.txt, lxml started failing. The first
failure was:

```
pkg_resources.html
      Building lxml version 4.9.3.
      Building without Cython.
      Error: Please make sure the libxml2 and libxslt development packages are installed.
```

Once libxml2 and libxslt were installed using `apt-get install`, lxml
failed with lots of compile errors. Bumping the versionfrom 4.9.3 to
5.0.2 fixed the compile errors.
