Add a repair issue when using MariaDB is affected by MDEV-25020

[bdraco]

Needs to wait for the MariaDB addon to be updated from 10.6.8 to 10.6.10 since users can't do much about this if they are using the addon.

Proposed change

https://jira.mariadb.org/browse/MDEV-25020

MariaDB fixed this in 10.5.17, 10.6.9, 10.7.5, 10.8.4. Previous versions would have history and purge queries running for hours which consumed all the available I/O and could make the whole system unstable.

@bdraco Just curious, have this been verified to affect MariaDB 10.3 too? Reading the MariaDB issue it sounds like it could be a regression in 10.5 and newer, but it's not really clear. 🤔

There are performance problems with purging on any version before 10.6.9. You'll probably never notice them if you have tiny database though (most people who migrated to MySQL did so because they have a large dataset though), but if your database ever grows to multi-gigabytes make sure you have 10.6.9+
