[5.4] Mysql installation Error Message

[brianteeman]

Summary of Changes

This removes invalid/outdated information from the error message. It should have been removed when Joomla 4 was released as the conditions that could create the mentioned error (< php 7.4 and Mysql 8) could no longer be matched.

By leaving this part of the message users are directed to an information page on the docs site with complicated instructions that are both no longer valid and very confusing and will NOT be the reason they are having mysql installation issues.

Technically our deprecation rules for language strings would require a completely new string to be added and the code in the installer updated to use the new string and then leave this orphaned string to be removed in joomla 7. I am happy to do that but it seems a pointless exercise to me. I leave that to the maintainers to decide.
