Tech:Updating an extension

This is a guide for updating any extension that we already have installed. While sysadmins can directly update extensions, users can make pull requests to update extensions by forking our mediawiki repository.

To update an extension:

---
 * On your PC
 * On the server

N.B.: Generally, you do not need to update an extension manually as Dependabot automatically creates pull requests every week. However, if you are certain that you need to update an extension and it should not be delayed for whatever reason (e.g. important bug fix that affects one or more wikis), you should follow the instructions above instead of waiting for Dependabot.
