fix: expose __version__ for LXML.

[farhaanbukhsh]

These changes expose the LXML version since it is used by libraries to check LXML version. We faced a problem in image-explored XBlock. Parsel needs to know the lxml version
https://github.com/scrapy/parsel/blob/master/parsel/selector.py#L35. Since this information was not being passed and etree flavor of opened.

Testing instructions:

1. Use Tutor to set up master
2. Clone [email protected]:openedx/xblock-image-explorer.git repo under (tutor config printroot)/env/build/openedx/requirements/
3. Add private.txt and add -e ./xblock-image-explorer in that file.
4. Mount this repository tutor mounts add ./xblock-image-explorer
5. Build the image tutor images build openedx-dev
6. Now start the dev environment with tutor dev start -d
7. Exec in the container tutor dev exec cms bash
8. Then run ./manage.py lms shell

In [1]: from xblock.core import XBlock
In [2]: XBlock.load_class('image-explorer')

11. This should throw errors.
12. Once you change the branch in the PR you need to exec in the container
13. pip install -e /mnt/xblock-image-explorer
14. Repeat 9 again, this time it will load without error.
