Add AWS Aurora MySQL 3.x for the k3s support matrix

Describe the solution you'd like
We need to validate K3s against newer versions of Aurora MySQL database:

• Version 3.x

We should validate this in versions v1.27 and above

This validation is stalled pending this bug fix - #10023

[VestigeJ]

Confirming good conformance checks from Sonobuoy against all recent RCs using MySQL 8.4 - (mysqld 8.4.0) MySQL Community Server

Will be re-testing this soon to validate.

Closing this as the only tests that failed with this database were resolved in the linked bugs
