[16.0][FIX] Prevent lxml import error

[Pexers]

Description

• As of today, using the latest version of the lxml Python dependency (currently 5.2.1) will throw the below error when starting up Odoo:

  Traceback (most recent call last):
  File "/usr/bin/odoo", line 3, in

  ImportError: lxml.html.clean module is now a separate project lxml_html_clean.
  Install lxml[html_clean] or lxml_html_clean directly.

Fix

• Use instead the lxml version found within the official Odoo requirements:
  • https://github.com/odoo/odoo/blob/c21be6c9cdc8500d96ae15c5f529598167a45365/requirements.txt#L23

Impacted versions

• All Odoo versions that use the latest for this dependency.

Sorry haven't seen your PR. I also created a PR removing the lib. #2897

I think your change won't work, because the requirements.txt is automatically generated and should not be changed manually.

But due to the broken repo, none of the PR currently can be merged. :(

Thanks for the feedback @CRogos , I'll close this one then. Hopefully it gets fixed soon. 🤞
