Upgrade MySQL to 8.0.29 to get CREATE FUNCTION IF NOT EXISTS ...

[jniles]

During our last release, we introduced syntax only found only in the most recently generally available release of MySQL 8.0.29. This is the CREATE FUNCTION IF NOT EXISTS ... However, SemaphoreCI does not seem to support the latest MySQL with their sem-service toolbox.

This issue is just a note to say that we should upgrade to MySQL's latest version as soon as it is available in SemaphoreCI.

Note that this is where we monitor the sem-service options:

Closing this as no longer needing a fix.
