Hardcode MySQL version

[jczuchnowski]

Latest MySQL removed --skip-host-cache flag but testcontainers still try to use it causing:

2024-03-29T15:45:29.779392Z 0 [ERROR] [MY-000068] [Server] unknown option '--skip-host-cache'.
2024-03-29T15:45:29.779894Z 0 [ERROR] [MY-013236] [Server] The designated data directory /var/lib/mysql/ is unusable. You can remove all files that the server added to it.
2024-03-29T15:45:29.779907Z 0 [ERROR] [MY-010119] [Server] Aborting

I've hardcoded the last MySQL version that has this flag.
