morphodict 2025: Upgrade repository dependencies to future-proof morphodict

[fbanados]

Current dependencies are approaching (or past) the end of their extended support lifecycles. Dependencies should be upgraded. For example:

• Django 3.2 LTS extended support ended in April : https://www.djangoproject.com/download/#supported-versions
• Python 3.9 to enter EOL in Oct '25: https://devguide.python.org/versions/
• Ubuntu 20.22 LTS standard support ends upcoming April: https://ubuntu.com/about/release-cycle

These main dependencies trickle down to other dependencies in the system. We should upgrade the morphodict code and infrastructure so it will continue working for the foreseeable future as it has been working so far.

Our expected timeline is as follows:

Name	Timeline	Ubuntu (infrastructure)	Python	Django	Node
~"Legacy"~	~End of May, 2024~	~🟡 20.04 LTS (EOL 2025-04)~	~🟡 3.9 (EOL 2025-10)~	~🔴 3.2 LTS (EOL 2024-04)~	~🔴 14 (EOL 2023)~

Updates on docker images and code will be reflected first on the dev branch

[^1]: Some dependencies (Django 5.2 LTS and Node 24) will only be released in Apr 2025.
