chore: Add step to upgrade to latest release before running DB Assembler tool (#523)

* Fix broken 'Database Setup' link

The page name was changed, but the link was not updated

* Add step to verify that you're on the latest release

* Use relative link instead of direct link to `database-installation` guide

* Reference 'upgrading to 3.0.0' guide instead of linking to github releases page

Per Kitznu, linking to the github releases page can cause confusion as people will try to download Azeroth Core from Github, which is definitely not what we want

* Fix typo

* Fix broken link: Add `.md` to the end

Oops 😬

* Update docs/Update.md

* Update Update.md
