An error is raised when trying to render date picker with the Mongolian
locale
Steps to reproduce:
1. Install Sales
2. Install and switch to Mongolian language
3. Open Sales and create a new quotation
4. An error is raised: `locale() locale mn-MN is not loaded from moment
locales!`
Solution:
Add the Mongolian locale. It is not present in the version of Moment.js
we use (2.19.3) so we get it from a newer version (2.29.2)
Problem:
The Mongolian locale was unintentionally removed in this PR
https://github.com/odoo/odoo/pull/111986 so we add it back
