[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 import odoo File "/usr/lib/python3/dist-packages/odoo/init.py", line 125, in from . import modules File "/usr/lib/python3/dist-packages/odoo/modules/init.py", line 8, in from . import db, graph, loading, migration, module, registry, neutralize File "/usr/lib/python3/dist-packages/odoo/modules/graph.py", line 11, in import odoo.tools as tools File "/usr/lib/python3/dist-packages/odoo/tools/init.py", line 16, in from .mail import * File "/usr/lib/python3/dist-packages/odoo/tools/mail.py", line 19, in from lxml.html import clean File "/home/odoo/.local/lib/python3.10/site-packages/lxml/html/clean.py", line 18, in raise ImportError( 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.

Apparently the problematic dependency was removed a couple of days after, so I'm closing this PR.
