New versions for MariaDB and PostgreSQL has been released
in the meanwhile, which falls into the supported range.

Also not considered for automated testing yet, support
to run it them at least locally on development machines
should be added.

This patch adds following versions:

* MariaDB version '10.6' and '10.7' for argument '-i'
* PostgreSQL version '14' for argument '-k'

Missed removing of no longer availabe versions in the
runTests.sh help text is done as side cleanup.

Example commands:

> Build/Scripts/runTests.sh -s functional -d mariadb -i 10.6
> Build/Scripts/runTests.sh -s functional -d mariadb -i 10.7
> Build/Scripts/runTests.sh -s functional -d postgres -k 14

Resolves: #97464
