[Tech Debt] Alias match functional tests

[ThomThomson]

Problem

Dashboards currently have an auto-redirect feature that activates when the loaded saved object resolves to an alias. This is most commonly encountered when a user upgrades from 7.x to 8.x when using Dashboards with soft links to other Dashboards in markdown panels.

Unfortunately, we've encountered a lot of problems with this alias match functionality, leading to four PRs targeting fixes to this system since 8.9.

• [Dashboard] Fix alias redirect & update error handling #159742)
• [Dashboard] Fix Alias Redirect Race Condition #161043
• [Dashboard] Fix missing state on short URL alias match redirect #163658
• [Dashboard] Only cache non-alias dashboards #175635

Fix

We should add a functional test suite which loads a kbn archive with reproduction data, and follows a markdown link to ensure the functionality does not break again in the future.
